Ex cheated on me over a year ago, I knew during the relationship and said nothing.

So ive been single for over a year now with my last relationship ending in a very messy way, i found out at least a month before it ending (by her choice of breaking up) that she had been sharing explicit photos with one of my (ex) best friends amongst other individuals. While I feel I’m over her and the feelings I had, I can’t let go of wanting to show her, prove to her I wasn’t just over thinking it or imagining things. Proving she didn’t get away with it but I know that won’t bring me any closure, and it won’t truly matter. It’s been eating away at me for some time now, the want, the need to be like “I know what you did, I know everything I know you lied and deceived me” but I chose to ignore it. Idk I just had to get this off of my chest I feel like it’s hurting my future relationships, I mean Jesus I’ve been single, celibate and failing every situationship I’ve had since then. Ugh. Thank you for listening have a lovely day everyone
