Sorry if the formatting is weird I am posting from my phone.

So this fuck up has been lasting a week or so. Lemme give you a little important information. My boyfriend and I started dating in December and I specifically told him no sexting with anyone but me in any way (snapchat, kik, etc). 

Last Friday I could not help myself and I went through my boyfriend's texts. I know it's like a cardinal sin but I had been suspicious for a while that he was sexting or rather had not stopped sexting since we started dating. Three of the four girls shut him down and he was drunk when he texted them. The fourth girl was a mutual friend who is in a an open marriage and was fully aware of my insecurities that he might still be sexting.

So over this last week we've been talking about it and he agreed to an open phone policy. Well I exercised my right to look at things and found two gay hook up apps where he had been sexting with other men the night before and that morning. I immediately confronted him about it. 

I don't even know how to feel about anything. I know he's bi and I know he's got trust issues too but damn this sucks.
