Please help boyfriend troubles?

So my boyfriend went on to my facebook and found a message from this kid that i didn't know and alls i asked was "do i know you" the kid never wrote back i wasn't attending on anything at all just simply asking a question and im bending over backwards trying to do the right thing i deleted my facebook and hes not forgiving me i feel like he likes the attention im giving him and he gets pleasure out of the torture hes putting me threw he knows how sorry i am and how im doing everything ot make it better and hes not even appreciating anything im doing hes just making it seem like anything do is never going to be good enough. what do i do?
