Should i even consider this kid my "best friend"?

my ahem. "best friend" doesn't try to do anything to hurt me. but he has inadvertently hurt me many times. i had a girlfriend. she dumped me to go after him he rejected her but still it hurts to see someone dump you for someone close to you. his current girlfriend, who was a close friend of ours before this, we both liked one night he asked me if i was over her so he could date her. trying to be a good friend i lied and said yes so he could be happy. i regret telling him that. because i still care for her. and now i have bad feelings towards him for that. he also just doesn't seem to get me. he is very popular has countless friends and could date any girl he wanted to, hell he's already been laid. and then there's me. quiet very little friends and more of social outcast. and more than likely clinically depressed. all of his friends, are very popular and have large circles of friends and don't have much pain in their life. i do. he doesn't know how to respond to me if i'm not in a good mood, therefore i really find myself having to pretend to be happy in front of him. lately i've been questioning our friendship and wondering if he's even worth my time anymore. can someone please share their opinion with me on this?
