A bit of a rant. Sorry.

So my boyfriend has been unfaithful in the past but I have never been able to substantiate actually proof he was physically unfaithful, just emotional cheating was all I had found because she called him while he was sleeping one night so I looked. Found texts between him and his ex while I was pregnant. I wanted to end it but he asked me for another chance, apologized, and said nothing he hadn't seen her and that nothing beyond texting and on the phone had happened. This was in April 2017. He blocked her number and I thought it was ended but then thought it picked up again but I had no proof and couldn't check his phone again. Fast forward to August 2017 when our baby was born, a week after being home from the hospital his phone was streaming to the tv and I was curious so I looked through it and found all this bs between him and her up until the Tuesday before my csection which I had on a Thursday. It wasn't anything good and there were sexts. I woke him up and was crying upset he told me nothing physical happened blah blah, I didn't truly believe that but again I chose to forgive him and put the past in the past and tried to make a fresh start. Now I know she has since became involved with someone who it is now serious with and I truly don't believe that anything is going on with them anymore, but I think he is cheating on me with someone else. 2 months ago I was doing laundry and I saw 100% cum stains on black boxer briefs because they were inside out. I confronted him and he lost it on me, telling me I was a bad psycho and crazy I told him they were inside out and I couldn't not notice it. Since then I haven't brought it up because it was such a bad fight the neighbor came over to make sure everything was okay. I haven't brought it up since because I don't like to deal with the fight that will come with it, but since seeing those stains now I do look. I am just so upset because I know he is cheating and it kills me. His van was broken over the weekend up until yesterday so he was home and obviously no stains then goes to work today and now there are huge stains when he comes home after working all day. I want to say something but I can't.
