Do any of you obsess over past emotions? I remember feeling something a few years ago and I’m now obsessing it was jealousy. It’s interfering with my day and I can’t stop thinking about it

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

Do yall ever reread old texts from a toxic ex and try and “solve” stuff constantly? We ended things 4 months ago and every day I go through old texts trying to prove I wasn’t the bad one, make SURE she was toxic, “solve” a random toxic moment I remember and make sure I have ALL the details remembered accurately and that I’m not misremembering it. It’s like im still living in the relationship. It’s draining and will not stop. Is this an OCD thing? How is it fixed?

With real event OCD, I don’t know if any of you feel this way, but do you ever feel that the past event(s) that you ruminate about or constantly obsess about are gonna come up in your future and just absolutely ruin you, that’s how I’ve been feeling for months, it just feels like impending doom, and I hate having to even think that my future would be ruined by what I did as a teenager, and I did some dumb things, that I regret so deeply, I just can’t stop thinking about that.
