Ive recently discovered that my fiance has been looking up trangender tranual ads on the internet?

im upset over this as i dont know if he's acted on any of this and also i dont know if this means is he gay or not he has no idea i know about this and id be to mortified to ask him about this ive also seen an e-mail he's sent to one of these t's sayin he messes around with cross dressing and that he's interested in maybe havin a relationship im so upset we just had a baby a few weeks ago and r suppose to be getting married im too mortified to tell anyone else about this all id like to know do u think he"s cheating r is this just a fantasy.id also like to ad that i only came across the e-mail by accident and after that began to look at his laptops history and almost 4 times a week he's looking up these personals. please id like ur opinions and also i dont understand bein attracted to a guy that dresses like a woman isint it either ur attracted to men or women ur gay straight or bi?can someone maybe explain and ive no problem with whatever a person is attracted to im just curious.
