We're friends since a year. He opened up to me, he told me he feels safe around me and he trusts me. I had the strong feeling that he likes me, other people told me so too. He's protective and even a bit possessive of me (in a healthy way). But recently he started to avoid me. He's very distant now. I asked him if he's okay and he told me that he's fine. It drives me crazy to be honest because I think it's my fault. I can't remember I did anything to upset him. I like him so much and I don't want to lose him. I truly respect and appreciate him and I told him that. Why would he behave like this all of a sudden?
