My problem?

Hi, I haven’t posted in a while. I’ve been struggling for the past month, it’s been a mix of ocd flare ups and depressive episodes. I recently got into a new relationship, one I was not expecting at all as I had just broken up with my long term boyfriend over the summer and was expecting the cycle of being alone for a few years and then dating again. But anyways, my current boyfriend is amazing and so caring and sweet, I told him before we even started dating about my ocd and how I sometimes need constant reassurance and that it can be a lot to deal with it and that I can become clingy and annoying and he didn’t even bat an eye, he just said he likes me as I am and that he will be able to help and support me. We’re dating long distance rn as I’m finishing up college but we constantly text and video chat/call almost every night. My ocd has been constantly gnawing at that and it’s causing my abandonment issues to flare up horribly, I’ve told him a little bit about my ex boyfriend as he was not a very good person, he was much older than me (12 years) and at the start of our relationship he was amazing and said he could deal with my mental health issues (I know no one is obligated at all) but I would communicate to him that it scares me when he doesn’t talk to me for weeks at a time, and at first he said he would try to be better about that but then it turned into him saying I’m annoying and clingy and that I bother him and that he just wants alone time but during that alone time I wouldn’t hear from him at all for two weeks. He also stopped caring about my interests and said I was annoying when I would talk about them and would even get mad when I tried to talk about my day. Anyways being in this new relationship has caused me to fear that my current boyfriend is going to leave me, lost interest in me or that he’s annoyed with me and hates me, which unfortunately has caused me to give into my compulsion of reassurance so I’ve been asking him a lot “do you still like me?” “We’re still together right?” “Have I annoyed you?” And I hate myself for doing that. He is so sweet and I don’t want to be like this, I don’t want to drain him, i genuinely have never felt this way about anyone I’ve dated but it’s like he was meant to be in my life and we clicked instantly like it felt like we’ve known each other forever and I don’t want to lose him. My avoidance is getting bad and I’m trying to stop myself from pushing him away but I just feel so guilty and ughhhh it’s so frustrating. I just don’t know how to handle this, I want to be with him and I want to make him happy but I hate that my brain works this way.

I feel so bad I overthink abt everything my bf says and does. I think that if he doesn’t say x y z when I want reassurance then he must’ve stopped caring or is tired of me. I know it’s not the truth and he gives me NO reason to think this way. This is my first healthy relationship and I want to be in each others lives forever. I love him so much and I’m trying my hardest to manage these thoughts but I’m so anxious. It’s so draining I feel helpless and like I can’t go a day without checking his social medias. I want us to be the best versions of ourselves for eachother but idk where to start or how to manage this feeling.

I don’t know where to begin, this is going to be very long. But whoever responds I appreciate you dearly. I’m 20 years old, I’ve dealt with a lot in my childhood with abandonment and insecurity issues from my family. Aswell of not having a role model of a healthy relationship shown to me as a child. Me and my boyfriend have been together for 3 years, my first healthy relationship. Last year I discovered OCD (I am diagnosed but I ignored my mental health as a teenager like anybody would) I started to get these feelings that I don’t love my partner/he’s not attractive enough/ etc etc. I’ve discovered that it’s ROCD. I made threads on Reddit asking for advice googling for reassurance, all the things as one would do with ocd (as I’m doing now!) One day I woke up and that theme was gone, I felt normal in my relationship for about 4 months with no terrible thoughts. As of about 2-3 months ago, my theme switched. Now I have a fear he doesn’t love me, he’s cheating, he doesn’t want to marry me. It has utterly consumed me (just like my last theme!) I check his phone an unhealthy amount (guess what I never find anything!) He always lets me go through his phone, but as anyone would he gets annoyed and frustrated. I always am searching for signs if he’s acting weird, will get into arguments 24/7 because my brain keeps telling me he’s cheating, I get fake scenarios in my brain, hell I even bought Snapchat+ to stalk his snap score. But ever single time I find nothing. A lot of things trigger me and I over analyze everything, phone calls who his texting. When I do search his phone I check his EMAIL because of how paranoid I am. When I see things on social media about people cheating I SPIRALLLL But what really triggered me was this scenario, his family loves to joke around with me and mess with him at the same time, especially with our relationship, saying I have a leash on him etc etc making jokes (which I can take but when I’m in an ocd spiral and they have no idea something’s are triggering) anyways, we were out to lunch and his mother texts him “are u at some girls house” he told me straight away then responded “why would u say that” then she proceeded to say she’s messing around with him. And sent a picture of me and said I’m with Hailey at lunch, then they had a normal conversation after. Obviously this sent me into a spiral, it still bothers me. I was so upset and anxious, when we got back to his house I went through that man’s phone like it was my only job in the world. And I search EVERYTHING not one thing goes untouched. (I sound insane) anyways we went back to his place, then he called his mom to come in his room and asked why she said that, she felt guilty and said she was messing around she had her hands in her head (mind you she’s been drinking probably just messing around with him when she texted that) she told me not to worry ever about that kind of stuff because her son is not that type of man, she proceeded to leave the room then texted me about how sorry she was and didn’t mean to freak me out and felt like shit about it. Ever since then she’s been acting kind of weird towards me (not really) maybe she’s uncomfortable or there’s another women idk LOL. Anyways yea what the hell do I do I literally can’t function properly.
