old friend

when did he become such a dick? we were such good friends and hes gonna let the past break us apart. i thought we were over it and we moved on. hes always like this. i never ever did anything to hurt him. idk how to feel about him. im so mad but at the same time why do i feel bad? idk. but i hate how he switches up all the time. what i mean by switch up is change for every girl he dates. we were bestfriends.
