I have been bestfriends with this guy for a year. We were so close, we dated twice. In the past month, he has started ignoring me and acting like he hated me. But he's been hanging around with other girls. Is he trying to make me jealous? I trusted him with everything, and I don't want to loose him. Please help? Thanks in advance. :)

Have you talked to him about this? Only he knows what he's doing and why he's doing it. Time to have a chat with him about this.

Maybe he likes this others girl but the only way to know is to ask him.
