Relationship problems (Fear of sexual rejection)

I’m gonna try to make this make sense, and any support or advice would be great. I have a beautiful girlfriend, who I’ve been dating off and on for a year. We were really rocky but got our shit figured out 4 months ago and have been strong since. I truly love this girl more than I’ve loved anyone. And I know based off the sheer amount of ocd that has come up on our relationship, that she means a lot to me. Me and her were in a friend group in 2022 and we never liked each other. However she had a sexual relationship with one of my old friends. Fast forward to now I haven’t talked to him in a long time and I don’t see it as an issue. However… I keep having this vivid flashback to him touching her some kinda way in 2022. I can’t remember exactly what happened or the details but it’s running through my head. I guess this is retroactive jealousy but it’s really almost hurting my feelings. I wish it would stop but I know ocd doesn’t work that way. I just wanna be happy with my girl and not upset at her past experiences

Hi all, I’m new here and this is my first post. I was diagnosed with OCD back in March and started therapy, but was only able to complete a few sessions before my therapist had a baby. I have been in a relationship with my girlfriend for 11 months and I’ve constantly been thinking about her past. More specifically something she told me that happened while her and I were speaking. In just two days it will be a year since she told me about the fact that she was assaulted by someone she met online. ( we both met online). It took place while we were talking. Originally when she told me, she told me she had sex with a guy she met online she told me she went over to watch a movie and then they had sex. Recently after we discussed it since it was weighing on my mind, she revealed to me that it wasn’t consensual and that she was sexually assaulted/raped. She told me she initially thought it was sex because it’s what she was sued to from her last relationship. She was abused and assaulted a lot by her ex, and this thing was normal for her. She said she didn’t realize how bad everything was until after we had been dating and she saw what true consensual sex was. The problem I have is that my brain knows every detail of what happened but keeps blaming her for her. My brain keeps telling me it was her choice and her fault and it justifies it by saying that she went over knowing it was a possibility he would want sex, so therefore it’s her fault. This has been straining me for so long because I can’t stop thinking about it. Everything seems to trigger a thought about it. I know inside what happened and what led to it, but I constantly think about it possibly being something else. I constantly think about every little detail. It has led me to having thoughts of “maybe I shouldn’t date someone that did this” as it doesn’t match my definition of the “perfect partner”. I have no idea what to do anymore. I obsess over things she had done with her ex in order to be loved by him. Like drinking, smoking weed, etc all things that I am against. I know she doesn’t do this anymore and was coaxed into it, but I’m constantly overwhelmed by thoughts of “she isn’t perfect because of XYZ so I shouldn’t be with her”. I won’t go into any details about the assault out of respect for her. I feel I’m constantly fighting myself and every good day I have gets overshadowed by one bad day :( I cannot see my therapist again until August and it worries me a lot.

it started when i simply worried about my partner losing feelings because she was being a bit distant and so i obviously spiraled and started thinking “oh yeah she has to be losing feelings of some sort” she was only being distant because she was preparing for her confirmation party (this is important) and me and my friend hung out the same day and ended up walking to her house to say hello to her as a joke. but i was already way too deep in my spiral. right after that interaction with her, she literally reassured me right then and there that i was “cute” and that “she really likes me” but i was so caught up in the idea that shes losing feelings for me that i couldnt accept the reassurance and kept having intrusive thoughts that shes lying to me and that she doesnt mean it. but whatever, i wasnt THAT worried because her confirmation is coming up and she wouldnt lose feelings for me before something like that right? a couple days pass by and im at her confirmation party, shes being a little distant but only because shes tired (evidently too) and so i was still in a spiral. but then i met her family, and her mom let me have her number (in case i wanna schedule something with my gf) and that sparked a whole episode. i talked to her mom a couple times and started worrying about if what it would be like it i left my gf and how it would affect me and her family and quickly a thought followed up with all her physical imperfections and how much i dont like specific ones. and then another one came up. i saw one photo pf my partner and swore it looked like someone in my math class who isnt attractive. i managed to get rid of that thought the first time, and had to deal with the imperfections idea thing for a whole month. recently tho, the unattractive girl from my math class is popping up in my head again. i cannot get it out of my head, any advice? what is this phenomenon and also im pretty sure im the only person who has dealt with all of these thoughts.
