so me and my boyfriend have been dating for 2 years now and it’s been pretty good, except for a couple months ago when he lied to me about when he was talking to another girl. he would send her very sexual memes and say i love you to her and they were very emotionally connected. I found out about it because i was bored one night and went on his instagram, i know that’s kinda bad but at the time i totally trusted him so i wasn’t looking for anything in particular, but i ended up seeing there conversations. i got upset and so did he and he decided to stop talking to her, which i really appreciated. a couple of weeks ago tho, she started talking to him again and i feel really uncomfortable and i don’t want him talking to her because i don’t trust them together. he says i have nothing to worry about but yet i keep worrying. Also, i’ve changed quite a bit for him because i really like him and want to stay with him, but i’m no longer having fun and i don’t know how to tell him. so really my question is, should i tell him how i really feel and risk breaking up? or should i wait for a little bit and start to trust him again and learn to have fun again?
