My ex said he is dating someone else..m I'm broken

My psychologist tells me because my thoughts are based off of facts/ broken boundaries which is why I am having thoughts of am i in love , am I settling , and feeling guilty I should let him go to find someone who wouldn’t doubt him that I do not have rocd. She states rocd is intrusive , irrational thoughts not based off of real facts and I may have ptsd not ocd. He kissed someone else before we were official and he finds a certain type of female attractive that I find disgusting . So I spin about these issues all day long to the point I’m so unhappy with him and had to break up . It’s been over a month now but I’m still severely anxious and depressed The thing is I can’t stop thinking about this 24/7 with severe anxiety and depression and nothing is helping me . Can someone please tell me their thoughts

My last post I talked about what I had done and how I ruined my relationship the best thing that has ever happened to me and me and my boyfriend have been working on it and fixing things this passed month and he just told me we are single yet committed to each other we are giving each other space so he can make sure he wants this I’ve ruined it in the passed month from everything happening u have been pushing acting as if everything is normal and not growing it’s my fault it’s all my fault I broke this I can’t do this right I love him with everything in me and I just wanted to make things right I’m sorry

I’ll preface by saying he’s a brutally honest guy who doesn’t feel like there’s anything wrong with being honest. But um… yeah. He says I concentrate on the bad too much instead of all the good. I said I feel the bad is still there lingering during the good. He doesn’t compliment me like my previous boyfriends have unless I’m absolutely dressed to the nines, and even then, I can barely get it out of him. I’m a few years older than him. The other day, I asked him if he is sacrificing being with his type to be with me, and without missing a beat, he said “yes.” Basically, his type would be skinnier, younger, hotter than me (shocker, I know). I showed him a photo of myself that I liked, and he said “meh.” I tried to be confident and said, “well, I know it’s good, and that’s all that matters.” He asked what I liked about it, and I said my cheekbones looked good. He said he “only saw cheeks.” I said, “yeah… kinda hard to see cheekbones without seeing the cheeks…” He then proceeded to poke at my face/double chin, and when I asked what he’s doing, he said, “Trying to find the bones.” In the same convo, he said he hasn’t wanted to sleep with me because of my weight. Said he wishes he could see my waist more. I’m 10 pounds heavier than I was when we met, and that’s nothing. He’s gained way more in this relationship, but I don’t give him shit about it. He says “well maybe you should.” But I’m not gonna go insulting him just because he insults me. When I tell him it makes me feel bad, he says, “well I wasn’t trying to make you feel bad, so…” Anyway, I know it’s not just ROCD. I deserve better than this. But ROCD still makes me question myself. Mad af at him ngl
