How do you break up with someone who is ill?

I know it’s long but plz read :( have been having really bad ocd about my relationship and my partner and it has gotten worse and worse over the span of like about nine months I’d say. I do acknowledge there are flaws and legit issues about him and the relationship like there are with anyone but I also know ocd has clouded my judgement and perception by analyzing everything and compulsions. For a while I kept feeling this need to get out which I know was ocd. I was really scared to spend the weekend with him because I thought I would just be annoyed and irritated cause it’s been that way for a while but he also was going through a period of high stress so maybe I was resenting him for that and I also wasn’t communicating how I should have been when I was upset because I’ve done that too much in the past. This weekend I was told in therapy to just be in the moment and not have to worry about trying to answer the question of do I love him or should I break up. It did help but It’s weird cause this weekend ended up better but I also was kind of numb? Like I was enjoying myself but didn’t feel what I always have felt in the past? Anyway, I am really anxious because i feel like if I loved him I would be supportive of when his parents compliment him or when he does well at something when instead all I think of are that I’m not happy or annoyed because of things he does that upset me or make me mad and it’s like that’s the only way my brain wants to see him as a person. Or when he is upset it feels like I don’t care like I used to because I think of how he doesn’t deserve this when he does this or he shouldn’t have this when he is like this etc. Why does my brain automatically go there? That’s horrible! I feel like I should be excited for him, rooting for him. But it also feels like I do care for him? But my thoughts keep changing. I am afraid I only am with him because I love that he loves me and how he treats me. This makes me feel selfish cause I can’t do that. I notice I still like when he cuddles me and is sweet to me and does fun things watching movies etc. And that’s not how it used to feeel which scares me because I don’t want to be without him. I also love his parents am I only with him cause of how his parents treat me? I feel so selfish and like I have to tell him and break up with him cause it’s the right thing to do. I never used to feel like this. I’m scared. Is it possible I’m just I’ve been mad and resenting how it’s been cause he’s been stressed mix with my ocd? My therapist said relationships can go through phases. Can I fall back in love with him again? I feel like I have to try to start with someone else like this is too far gone. I don’t want to stay in something where I don’t feel toward him the way I want to but I really don’t want to leave him. I feel like such an awful person cause he doesn’t deserve this and is so caring and loving despite everything the major thing that bugs me is how he gets irritable a lot which is an imperfection that makes me get anxious and question him😭 trying not to read into this and just follow what the therapist said but this is scaring me because I feel like if I loved him I wouldn’t think like this or feel like this.

I’ve struggled a lot with mental illness (severe social anxiety, depression, OCD), but have done a lot of work to get to the great place that I’m at now. I feel like a different person compared to how I felt a few years ago. Here’s my question: I started seeing someone really important to me. We’re not official yet, but we’ve been in each others lives for years and it feels like it’s the real deal. He struggles with OCD, and it’s much worse than mine ever was. My question is, do you think this is healthy for me, as someone who has done the work to get to a better place? He’s not in therapy, he’s against medication (I love my meds — they changed my life), and is generally in a different place than I am mentally.

Everyday I wake up and start searching for reason to breakup with my partner. I feel utterly confused by relationships and dating. Not to mention, I’m autistic and this has always been a huge struggle for me. In fact, it led me to both diagnoses of ASD and OCD. I can see there are some things I am not happy with in my current relationship and I understand that, but when does it become too much? I started having limerence over a random person because my brain just wants an out so fast. I told myself that I wouldn’t until I get proper help (medication, constant erp therapy etc). Every time I think about breaking up I start sobbing and my body vehemently rejects it. Its really confusing and disorienting for me and cant trust a damn thought in me. I’m scared that I’m just taking him along for the ride and potentially will severely fuck him up emotionally because of this. I guess thats where I can feel the OCD. My fear of being a bad person and the people around me being bad people. I dont know if I need advice because I think this may be me searching for a compulsion to do. But I just want to get this out of my system. I have severe Disney-like unrealistic expectations sometimes. I had to maladaptive daydream all the time growing up to get out of my traumatic upbringing and brain (tbh). I still do. I am aware of that and try to put myself into check. I just cant stop comparing my friends own beautiful relationships to my own. Most of them are in the “engagement” stage of their relationships. Even though it’s ridiculous, all of them have worked on it for many years at this point.
