He has a girlfriend!

Hi, So I met this great guy last year. He is perfect, we became friends last year and I got very very sick and he made the effort every week to message me a fun fact that he knew would make me laugh and smile. He was genuine and very caring. This is when I started to get feelings for him, we started messaging and seeing each other more regularly, we flirt all the time (he initiates it) then all of a sudden he became really weird, that was when I found out he had started seeing his Ex-Girlfriend again (they broke up in late 2011 or early 2012). I avoided him for a while but as I am involved in the sporting club he plays for I see him at least 3-4 times a week. Recently the flirting started again, I have tried not to recipricate. He has also started messaging me a bit more, I have kept cool and collected and only answered questions asked, i don't try to keep the convo going, but since doing this he has been messaging me a lot more than normal. when we were both drunk 2 weeks ago we ended up sleeping in the same bed (he invited me into the bed), he hugged me and we held hands. Nothing happened but I still feel guilty, and I told him that. I see him all the time and I don't know what to do. If I avoid him he makes more of an effort.

Ever think about confronting him??I had kind of a similar situation with an ex who kept contact with me. I still loved her...I had to tell her, for my sake, I need ya to not contact me because my feelings go beyond that of a friendship...you have to be true to yourself...if you have feelings for him and the messaging is throwing you, maybe tell him that...And the messaging more when you ignore is classic want what you cant have behavior
