One night my fiancé came home and said “Babe, I almost.... Never mind” I questioned him about this statement the next day and he stated that he doesn’t remember saying that. So of course after that I felt uneasy.. A couple days later he was at his friends house and he snap chatted me and started talking dirty to me asking me to send him nudes. So he came home. The next day as I was getting ready for work, I picked up his phone and opened his snapchat. He was also messaging his ex around the same time he was writing me asking for nudes. Snap chat is supposed to delete messages but sometimes it doesn’t. I opened the message and I saw that he wrote her “I’m trying to fuck you tonight” and she responded with “Boy Bye!!” basically telling him off. At this point I was livid. So I questioned him about it and he said thay night he came home and said “I almost...” he says that she came on to him and he told her off and he admitted to asking her to fuck him that night. This specific ex girlfriend is his sister’s best friend so obviously, she’s been around longer than I’ve known... I’m happy that he told her off the first time but the situation is just really sketchy to me.... What’s your opinion?
