A couple of days ago my Boyfriend got in an argument with his friends girlfriend over what he should be feeding his dog it was ridiculous and petty but she ended up calling the RSPCA who came to the house and said what we were feeding the dog was fine. During the argument my boyfriend had called her some nasty things over text message which prompted her boyfriend (My partners friend) to come over to talk things out. things got heated and while they were outside I decided to see exactly what was said. (He called her a bitch) while on his phone my curiosity got the better of me and I scrolled through some of his other messages on snapchat where I found that he had sent nude pictures to a girl he played xbox with. After I confronted him he said it was a momentary lapse in judgement and that the sexting lasted a day. I also saw that he had been chatting with an ex colleague for a while and that she recently admitted to wanting to be with him and telling him to leave me for her. He told me that he blocked her after this came out a few days prior to me finding the messages. I am trying to give him the benefit of the doubt as although finding out he was sexting someone else has been really difficult for me I do love him and see a future with him. I'm feeling really insecure and I don't know if I should keep it to myself and work though that on my own or talk it through with him or someone else. I know he's ashamed and remorseful about what he's done but he wants to move on and act like it never happened. It's humiliating going through this right now which is why I haven't confided in my family or friends and I already know they'll tell me to leave him. I've already made my mind up on trying to work through this but I'm not sure how to.
