How to get my ex to see that i still care?

okay I broke up with my ex because he didnt give me any attention and he was being an asshole to me... is it right that I started going out with someone 3 days after we broke up...hey is not like I randomly picked the guy we go way back ,,,but now my ex...

hates me he says that he doesnt care about me anymore and he ignores me , I think his being imature because told him that I wanted to be friends and he said no but I really do want to be friends with him cause I care about him... what should I do??

I dont feel that it was completely wrong for you to get a boyfriend 3 days after you guys broke up..but I mean he probably feels that you didnt really care about him bcus if you did you wouldnt have moved on so quickly...on the other hand..he really cares about you...he's just sayin that because he's mad at the moment but im sure that once things cool off..he will let you know that he really did still care about you...you probably broke his heart

well getting a new boyfriend. three days after breaking up isn't right...but I cant blame you bc I got a boyfriend before breaking up with my current one...anyways the right thing would have been to wait ...but its too late now. so all you can do is wait until hes in the stage of being capable to be your friend. it'll take time but dont worry he'll come around and you guys will be able to be friends eventually.
