A break up

So recently my boyfriend just broke up with me (like 2 weeks ago) and he already has a new girl.....here's the thing I texted him the other day basically saying hey I'm hurt and I miss you and I'd anything to be with you again.....all he said was sorry I can't have a girl which makes no sense because he has one now like what the actual fuck......he also won't tell me why he broke up with me and it sincerely bothers me.....I also think he was talking to this girl while we were together which also really hurts I just wish I could get over this more quickly seeing him being fine while I'm an emotional wreck hurts the most
