I had dated this guy for almost two years when we broke up over a year ago. He started dating someone else soon afterwards and we didn't talk to each other for a while. He's contacted me out of nowhere to wish me a happy birthday, make random conversation, whatever. A few weeks ago, we were talking and he wanted to webcam with me. He got me to play this stupid game in which I would ask him questions about myself and if he got them wrong he would take off a piece of clothing. Needless to say, he lost and I don't need to really go into that much detail because what he did after that was extremely inappropriate and something that shouldn't be done in front of someone you're not dating. After that incident, when I called him out on it he was like.. "oh, it was my out of control hormones". He then told me that he would like to be friends again and he promised not to do what he did again. Even before this happened when he would talk to me, he would always ask me sexual questions that would leave me kinda grossed out and confused. I have no feelings towards him whatsoever, all I want to know is why would he do something like that when it's pretty certain he's still with the girl he started seeing after we broke up.
