Should i wish my exboyfriend a happy birthday, when he doesn't even bother to at least say hi on FB?

He doesn't even deseve my whole presence...on he's facebook..well dumped me for someone else, 2years ago,because he liked someone else, common things this days, but he also wanted to remain friends with me on myspace, he requested me two times, 2 months latter after the brake up..and a year latter, so thats why i decided to request him back, since im over what happend and what he did, he's request made me think that he cares for me, somehow...when i added him he said hes ok and that hes on college, i also commented hes status once...he reply on a playfull way, but after this im not talikng to him anymore, i feel like he added me..just not to make me feel bad..
