I found out about 7 months ago that my fiancé, relationship of 4 years had cheated on me. I actually found out about a few weeks before my 21st b-day and was very devastated. We live together and I knew there were times where I found him flirting with girls on social media and confronted him about it but it was always nothing and I would let it go. I was starting to lose my trust in him and one night when he was asleep went through his phone, which I know is wrong but it was really eating me up inside. When I did I found naked pics of girls from dating apps/sites, texts, numbers, calls, FaceTime screenshots, FaceTime logs for hours of time, most when I was probably in the house asleep or at work. We got in a huge argument and he just kept saying it was because he was bored and liked the attention. I stayed in the house with him and was very angry but pretended like it was something I was trying to get over. Then about 3 months ago I found new pictures and another dating app on his phone and confronted him, he told me it was old from an old phone but with Apple it has the time/date stamp on all pictures. He finally said he was done, he was changing. However, I'm really really distraught over this whole incident. I'm still with him and we still live together. It's hard because I don't trust him at all but I truly love him more than myself. I literally do anything and everything for him, plus it's been 4 years that will feel so lost to me. I'm not really sure what to do. I haven't told really anyone in my family nor his because it just hurts. I've only told two close friends and mainly got judgement from them for staying. I just feel so hurt, alone and confused. What should I do?
