Very jealous, very competitive. Review the relationship, this type of person enjoys when you are in trouble, down, sad, losing,stressed... Might be good to distance yourself, find friends that are happy for you.
You Don,t say how old he is,maybe he is immature. I would said jealousy is his nature I wouldn't let this bother you. you have better things to do with your life,and happy someone thought of you to give them huh?
