Ex boyfriend

My ex boyfriend and me broke up about 2 weeks ago. We both desided to break up so it wasnt like one of us was insanly hurt. After we broke up his sister said he has been in really bad moods, then she said he has started talking to this girl a lot and she...

says he likes her she thinks. So I figured that he was probably in better moods now because hes moved on or somthing but she says hes still in bad moods.
Is it because of me and him or what? Hes confusing me.
Im still single and I havent gone for rebounds or anything.
Any ideas?

It if was ment to be, it will be. If you really like him, you should be patiant and move on. If he's seeing another girl, you should really move on. Don't wast your time on him.

I have moved on, its him im worried about
