When I first started dating my partner, he was still in contact with his ex. I was ok with this as I didn't know what she was like, I naively thought she'd be one of these nice ex's that is accepting of old bf moving on, how wrong was I.
As soon as she found out he was seeing someone new and it was going somewhere she started up, begging for him back, constantly messaging him, ringing him and giving him shit for ignoring her. It wore me down as I didn't want that kind of hassle.
He eventually blocked her after 11 weeks, I knew it wouldn't be the end of it. Lo and behold, a few weeks after he blocked her, she turned up uninvited claiming to have moved on. I found out and went mental and he then re-blocked her.
We started to move on, but a month later I was having a discussion about it with my niece, and it opened up that wound and from then on, it's been on my mind constantly. I'm finding it so hard to let go of the upset. I know he's with me and he says he's so much happier. She was awful from what I've heard, jealous, possessive and really insecure.
I want to forgive him but I feel that by doing so, I'm saying "What you did is fine" I don't believe he'd do it again. But there's that distrust. (I trust him with everything else) we have an amazing relationship but this ruins us, I'll bring it up and it's always the same "why did you do it" "why did you let her in" I just wanna move on from it.
