I really like this guy and I thought he like me to so I ended up giving him head and it wasn't as he expected it to be because it was my first time and afterwards he became very dry but then start asking when we're going up have sex. I told him that I start to feel like I was being used and he told me that I shouldnt catch feelings and he thought we were just practice buddies it was something completely different than what I expected. I was really upset and so we started being really dry to each other and I found it today that he has a thing for some other girls. I feel so hurt and disgusted what do I do
