Me and my boyfriend have been together 4 years. 2 years ago we moved in with each other it was too soon and it didn't work out. i suspected cheating happened. We broke up i moved out early, he slept with the girl i suspected less than 2 weeks after i moved out. He also slept with another girl 2 months later we get back together. He denies the cheating, said it was only flirty with the first girl when we were together so i got back with him knowing how i felt on it, i wanted to work on things so did he. All last year we rebuilt and worked on things. September he gets a new temp job, all year he's said he wants to make new friends and he does at this work place. Suddenly he's on his phone a lot and going out so i ask. We had a mature reassuring conversation about it he understood my anxieties on it. but we talked it through. I will note i do have mental health struggles with severe anxiety. Anyway i noticed a girl he was speaking to a lot. Due to my insecurities i was uncomfortable. he's talking to her, day to night everyday. He's become quite close with a few people now. This girl is sticking out to me. On NYE when we were with friends he was just on his phone talking to her. i called him out. In January we are in a very rocky place, egg shells. I've started therapy to help myself.. i go through his jacket and in his wallet was picture of him and 2 friends one being this girl. He has his arm around both (fine) but she's gone up and held his hand. I Confront him and like i said last egg shells so we took some space. We talked all night we are both going through it emotionally but want this to work, but why take a picture like that when trust is being rebuilt. from then till yday he's been very reassuring showing how much he wants this to work. Yesterday i found a valentines day card from this friend expressing in a paragraph how much he means to her and calling him hot? we have both been going through it, if he wanted to leave he could. why entertain this?
when i confronted him, he said he thought it was a thank you card for coming to one of her shows recently. He said i won't understand the dynamic but how can i when I've not been introduced and if thats your dynamic the its very inappropriate.
