It means that he is not your boyfriend!
go out and get yourself a real boyfriend
shoot him in the head
Personally, if you have feelings for him and like him don't dump him. I mean you can dump him but if he dumps you than you can ask him why.
Dump him before he dumps you.
move on you can find a better guy
No, as long as he is good and not cheating on your sister or anything
Yes, it helps you to get everything off your chest.
You are not related to your boyfriend's sister, although you and she may be friends. If you were to marry your boyfriend, she would be your sister-in-law.
She is all happy and not cranky and she is in a good mood and she starts sucking up to people that she never did before.
NO its not ok to date your sister ex boyfriend that nasty to date your sister ex boyfriend i would never date my sister ex boyfriend and i hope she wont date my ex boyfriend
Well move on get a new boyfriend make him jealous if you want him back !!
