Putting pressure on my partner + relationship

Posting here for the first time, please be gentle, not sure if this is applicable! I definitely struggle with reassurance-seeking especially when it comes to real events, but over time have found ways to self regulate and use self-guided therapy apps and worksheets to help fight any challenging thoughts as they come up throughout the day. There are a few times when I’m unable to do the work myself and don’t feel as emotionally strong, which I feel is reasonable considering how exhausting my symptoms can be (for clarification, I am diagnosed with anxiety but not OCD, although I fear all signs lead me here). Only on the extremely difficult days, I’ll ask my partner for reassurance (he is aware of my tendencies and is quite patient) but he has his own baggage, and having a partner asking for reassurance can be triggering for him, as he was accused of several negative things in his last relationship. He quickly gets overwhelmed with me and feels that I don’t trust him. He is convinced that is the motive of my reassurance seeking. Today in particular, I woke up from a nightmare that reminded me of a past event. After struggling with it myself all day I brought it up in the evening to try and get some help, and did bring it up three times after that. I am always soft and gentle when I ask for help, and even asked for a lighthearted “pinky promise”, which actually seemed to bother him. I understand that it’s not his position to emotionally support me whatsoever and that reassurance seeking can become harmful to the both of us, but for the one-off days where I am having a really difficult time, I feel extremely unsupported by him. For context, my partner has broken my trust before. My thoughts took off during that time. It’s been a few months since then, and me openly seeking reassurance from him is not a frequent occurrence, since I’ve started my self-help. I actually feel I’ve come a long way but I do have days like today that set me back. I love and trust him with all my heart, but man does my inner monologue make me work for it. I just don’t know how to get him to understand that it’s me having to work for it, not him. Unfortunately from the way he reacts, I’ve grown to feel unsupported by him, and am now rarely emotionally vulnerable with him. I am curious if there are any suggestions on helping him help me in a sense.. I don’t know how to get him to understand that it has nothing to do with a lack of trust. I have briefly opened up to him about my strong intrusive thoughts and figured it would help him understand a bit better but I don’t know what to do. I want to add: I have tried talking to him about how I felt unsupported. He just tells me he feels accused and would be supporting me at his own expense. He has even told me that I shouldn’t talk to him about these things, even though the thoughts I struggle with are directly related to events in our relationship. I really can’t seem to get through to him.

My partner has an anxious attachment style and it's been really hard for me.. I am polyamorous and so I usually see him half the week. He knew this going into a relationship with me but it seems he feels he never has enough time with me. I try so hard to make him happy. There was this one winter break I didn't make plans with anyone just so I could maximize my time with him and he was still unhappy. I'm trying to see my family again after fleeing for over 2 years because of an abusive family member I had. Its gonna require some of my time on the weekend and he said he'd support me but I'm scared to bring it up every time. He can't afford to see me as often anymore bc of the ware and tare on his car. I'm so worried I can't make him happy. He's even struggled with SH at times I've been gone. He says it's not my fault and it's a lot of factors but I can't help but to blame myself. I want to see more of my family again for the 1st time after 3 years next weekend, but I already have another commitment with my step dad. My partner is also always afraid I'm cheating on him, which I would never do. He's just been cheated on a lot in the past but it's hard for him. I just feel terrible about myself bc it feels impossible to make him happy. I don't really want to be judged for being poly, I just have relationship anxiety and I hope I'm not alone.

Everything feels Like its falling apart at the Moment. I am faced with Lots of unprocessed trauma and flashbacks in my Relationship + this stupid pocd that latches onto my Partner. Even if I Just know and she has also OCD, Anxiety, maybe autism BC she cannot read emotions or reacts Sometimes too rational, she understands me best. She understands my illnesses and intrusive thoughts and in the past she got triggered by the pocd also a little bit. Just the disgust Feelings, triggers in some Situations and Compulsion to Look away and some what If thoughts.... It didnt get much worse but I maybe constantly reminding her of some stuff because I have to hold myself back from Compulsions.... She opened Up over some stuff that happened in her childhood and over the Last weeks it got worse and worse in my case BC of triggers of my own childhood Trauma and Trauma in General.... And she is a mirror.. I feel constantly unloved or unwanted, I am so impulsive, I insulted her in Arguments as a p..... Such stuff... She does Not leave but I feel that she has no Energy left either... Before a few days it heated so much Up that I was outside until late at night.... Slept on the Couch.... Next day the Argument continued... I h@rmed myself .... I also hurted myself thursday night with a plastic bottle but on friday it was with a kn*fe.... She called ambulance.... I Had to Go to Hospital.... I never went with an ambulance to Hospital.... That day when I was Back WE Had a good afternoon and it was okay.... Saturday was okay too Just the night.... I have some disturbing Feelings BC the OCD and everything impacts our seggs life .... I offen feel unwanted or undesired.... Misscommunication can lead to arguments... Yesterday in the evening it got worse after a day that was alright.... I was Feeling Like leaving but I stayed outside and she was so upset she didnt let me in... Then we chose to pause the argument... Today it was alright I think but I was so worried what to do If I should Work tomorrow again bc I am sick since a week..... But on a walk outside it was hard to speak without getting upset... So I Said I wanted to walk alone and she should Go the other way... After a few Minutes she was gone... I don't know where she is since Like 1 h 40 Minutes.... Tried to send WhatsApp and call but she isnt online.... Thought she wasn't at Home so I didnt Ring the bell and now I am sitting at MC Donalds.... Maybe I try to Go Back to the House and Look .... If she is there.... I barely have Energy for myself how should I Take Energy for her and the Relationship too? Pls send advice. Kind regards. Jal
