I have recently become obsessed with the thought that my partner cheated on me. Years ago (2017/18) I went through a really low patch with my mental health and really pushed him away. I had counselling eventually and worked through my feelings which weren’t really anything to do with him or the relationship and things were a lot better. Around this time I found a hair bobble behind our bed. I know this sounds innocuous! But it was 100% not mine and I hadn’t had any friends to stay over in our room so couldn’t be that. I asked him at the time where it had come from and he said he didn’t know and I left it at that. But recently I feel like I had a wave of realisation come over me that he had cheated. I was quite close with one of his mates wives at one point but we drifted apart. I can’t help thinking she knows and feels bad and so didn’t want to see me anymore.
I cannot stop thinking about this, I know the logical thing would be to talk about it but I feel like that is something you can’t take back. My mental health hasn’t been great this past year and I am wondering if obsessing over this is a symptom of that. If anyone has any advice I’d gratefully receive it!
