Apologies that this may seem childish but I need opinions.
My best friend came over to my house last night, and told me that she had sent a snapchat to around ten people, and that list included the man I have been seeing for about four months.
This is not odd behaviour in itself because they were friends before I met him, and they work in the same office about one day a month.
Anyway, she went on to tell me that the snapchat she sent was a picture she'd taken in bed in a black lace nightie with one of those filters with the ears. Apparently the guy sent her a message the next morning saying 'nice nightie' with a laughing face, and my friend asked if he was taking the mick, to which he replied that he was giving her a compliment.
I should add that I broke up with my husband last year after I found him having sex with someone I know in my house. Obviously I don't trust anyone easily. The relationship between myself and the man is serious and exclusive, we are not official because I'm not divorced yet, my decision.
Anyway I got angry with the guy, said the comment was inappropriate and hung up on him, he turned up at my house saying he didn't think before texting and he apologised. He gave me his phone to read his messages (I didn't).
Best friend is angry at him for not speaking to her and trying to sort it out. She also accused me of taking his side and said we wouldn't be as close because the guy had pointed out that I didn't get these pictures so was I sure they weren't just sent to him. She said he'd made me doubt her intentions.
Honestly I don't know who trust. Was a snap like that in appropriate if it was sent to many people? Was his comment him trying to flirt? I said I'd step back if he wants her but he denied this and begged for my forgiveness. Should I just stop talking to both of them? I don't know if im overreacting, I doubt my own judgement because I know I have trust issues. Aibu to doubt them both?
