Me and my fiance have been dating on and off since we were 12 we are now 24 with a little girl. I caught him last mth posting and replying to ads on craigslist to both men and women. He sent his pic nude to both sexes as well. He was also caught on dating sites. When I caught him he swore it was nothing and he never cheated or did anything with them and him telling them he hated me with a passion was a lie to them....he said it was to see what people say I guess...he also responded to a girl wanting a daddy it was so visual as we have a daughter.....it was nasty to me....i asked how long he's been talking to other people in general he said maybe a few mths well I got on an older email he had he's been randomly doing it since 2014....what should I think? He says he's straight but was very into men on craigslist in the conversations...says he talked to them do to things we were doing in the bedroom...but doesn't remember emailing the girls....HELP :(
