So my partner and I both 20 have been together since we where 16. It was all great but just over a year into our relationship I cheated I was talking to another guy for about 2 weeks and kissed him once. All while he was working away on an apprenticeship. I never told him however he saw messages on my phone and confronted me and I lied and said nothing happened. He belived me and moved on. Some months later he kissed his ex on a night out and I found out. He broke up with me but soon after we got back together. He then kissed a girl best friend a year or so later. We didn’t break up. I was hurt but moved past. Lastly her was texting and sending explicit pictures to someone about 10 months to a year ago. I was devastated but didn’t leave.
He has only recently discovered what I had done but I have her done anything like that again and would never even think of it. But he now only sees me as someone who would do that. We are both young however before this we where very ready for life talking marriage and house.
I feel awful for what I had done and he feels shattered but I feel like we should be able to move past. He says we will and then in the same day will get really worked up and say things that really hurt.
I want us to be able to move past and build the life we had planned. Advise ?
