My partner is poly and I have realised I’m not..

For context when I first started seeing my current boyfriend I was in a ‘poly’ relationship.. (I say it that way as the guy said he was but was actually just cheating on his now wife)..

I have since realised that I would struggle with being poly as I have been screwed over so much in the past, my boyfriend and I had an argument about this and that I don’t trust anyone 100% because of this, even my closest friend. I just can’t, I have to keep that safety wall to not be destroyed again.

He got so angry and that I should trust him fully and that he would talk to me if it ever went anywhere with someone, well what a surprise, turns out I’m right not to trust anyone as (terrible I know and I brought it on myself) I looked at his phone and he is really flirting with another woman, not just compliments but about toys and play… he said that he doesn’t flirt with anyone because it causes a negative reaction and said to my face there was no one else.

Honestly I’ve realised that there is just no point in being with anyone monogamous or poly as everyone lies and cheats and proves me right in the end.

This may not even be the right place for this but I had to get it out
