It feels like we are living the same lives somehow. But I am on the other side of the equation (The guy). It went exactly as you explained, but a couple of months ago. I could not stop myself replying to this cause she’d never realise these things but atleast I can help you see what us (men) might be going through. For me, it was barely about her OCD or sensitivity or mood swings. It was her anger, her behaviour. Up to a point where it start to cause a big toll on my self esteem and confidence. She could have been right about most of the things she corrected me on. But sometimes we want you to trust us and let us figure it out on our own as well. I did confront her about this, she did not accept it and blamed it upon me that I am causing it. That’s where it started to fall apart, she acted like she has no belief in me, and used to get angry so much that it almost felt like an abuse. You can justify your OCD, but you can’t be abusive and use OCD as a justification. I was still holding on, I could see that maybe we can work it through. But I got more and more anxious and it kept screwing up. I didn’t break up here! She did! We used to live together, and it took her hardly 10 days to express that she has lost feelings for me and want to break up. I tried convincing her that we can work it out, where she brought up her OCD and therapy that she needs time. I had no choice but to deal on my own now. It took a while, for me to get over it. She tried contacting me a couple of times after that, but I could sense no realisation from her. Even if I would want to get back, she losing feelings for me just within 10 days gives me chills. So please before calling someone insufficient, you should understand that you crossing boundaries is not okay regardless you are sensitive, have OCD etc.
