Some background.  I'm a straight guy, she's a straight girl.  She's really close with a guy who used to be bi, but is now "strictly gay."  I just find it weird and a little creepy that she will cuddle with this guy.  I don't know if I'm being irrational and should just let it be or if I being a little upset is normal.  She says she's not attracted to him; I'm not scared of him trying to take her from me or anything.  I hope I don't come off as homophobic, I just think it's weird for her to cuddle/sleep in the same bed with another dude, regardless his orientation.
