I probably sound really dumb, but this has driven a huge distance in my relationship because my trust has been broken. My bf lied about going clubbing, he’s never lied about it before. I got a message on Instagram from an account that stated that he was at the club and kissed the guy who’s been messaging me girlfriend. I didn’t believe the account at first, showed my boyfriend the message and laughed about it whilst I blocked the contact because I trusted him so much. A few hours later the same person on a different account send me a photo proof of my boyfriend being at the club that night. I went on the club website and it was in fact from the date he said he didn’t go. I didn’t mention anything to him and asked him again where he was that night he said he was at this friends house. I then confronted him and he said okay he was at the club he but swears he didn’t kiss anyone but he was black out drunk and doesn’t even remember the night properly. the account that messaged me said he called the girl that night. I asked to go through his phone. He did in fact call her. However it is weird because the name was saved as something else but I knew it was her because the Instagram account gave me her number for comparison. I asked him why he called her and why her name was saved as his friends name, he said it was her nickname and he must have called her by accident when he was looking for his friend at the club. Which doesn’t make sense. He had her on Snapchat. However, she is someone that is friends with a mutual friend we have. He said he knows her from the past. I messaged the girl and she said it’s true they kissed. Then I got information from another person that apparently her boyfriend who was the one to message me on Instagram controls her account. I’ve asked several people that were at the club that night that I don’t necessarily know too well some said he did do it some say he didn’t. His friends all deny it. I don’t know what to believe anymore I love him and trusted him but I’m just confused on what’s true and what isn’t and it’s honestly driving me apart from him I don’t know if I can trust him again.
