I brokeup with my boyfriend a month ago, and 3 days ago, hes been acting strange during class. My best friend was joking around asking him for a hug but he refuses. Suddenly he runs up to me with a very tight long squeezing hug. He was also invading my space and throwing things at me. Today, I was being nice to him and one of my friends asked him if he wants to get back with me. He does not give an answer. He says "maybe". I really miss him and don't want to lose him. It's confusing.
