husband

So...  sorry this is such a long post in advance... but in the past we've had problems with him snap chatting and talking to other girls, and then he finally stopped with that girl, then he ended up doing it again and kissing a girl, from there we split up for a bit, and then we got back together, things were fantastic and have never been better. I then seen he was texting one of his friends exs saying stuff he shouldn't and we fought about how he doesn't know how to talk to women and he deleted and blocked a lot of girls from his phone and some social media. Things seemed to be better and I looked at his phone periodically and never seen anything until the other day, he was in the shower so I looked at his Apple Watch, and see where he again was talking to a woman saying things that are not ok to say to another woman, I asked him to delete her and any other women he doesn't know on EVERYTHING, he just keeps saying he hasn't had time because he's working and stuff, and him learning and not talking to women in that way is something he has to work on, which I asked why he feels he needs to work on it, it should be something he just does, and he said he hasn't done anything. He also likes girls pictures and crap all the time, idk if I'm just being crazy or if I really have a right to feel so hurt and everything the way I do...? I've gotten to where my self esteem has gone way down and I now feel as if I'm not good enough and not pretty enough because I know those women are much prettier... I HATE this feeling though
