Do i ask him back out?

My boyfriend and I broke up 2 years ago.He came back to talk to my brother about a year later. I thought I was over him but it turns out I still like him a lot!!!!I knew I wasnt over him when he started flirting with this girl up the street(he lives 2...

houses up the street from me)I could not stand it.I was jealous every one knew that I liked kim and I didnt care.He knew and I wanted him to.SO this girl deciedes to rub it in everyones face about how they were going to go out. then all of a sudden this my so-called friend came out of no where liking him and I was mad because every body seems to like him.I was ready to move right back to my old street because there weren't any fake people. I dont understand him because one minute he's smiling at me all the time and wanting to play basketball and then when we play he's feeling and touchin all over me playing defence.Then the next day he wants to flirt with everybody and forget all about me and then my brother says that im stupid and I need to get over it and believe me I try but I cant do it I don't know why I just cant get over it like every one else does.He claims he does not like me but every one else says he does like me. Please help me!!!!!!! Should I ask him myself or just let the past be the past?

well i thnk u shoould go over why u guys broke up and if it wasn't anything serious, i'd advice you to ask him out again. there's nothing to lose
