Question #21:
I had a guy friend who trusted me with a lot of secrets and everything, and we talked all the time, but then all of a sudden, he stopped talking to me. Was it something I did, or is he just a jerk?
It could be he started to like you, and didn't think you felt the same way, so just decided not to talk to you anymore. Or it could be the oposite, and his friends made of him saying he liked you, so he stoped talking to you to prove them wrong. If you have his number, try texting him or something saying you miss seeing him.
