Why would an ex start to date one of his female friends shortly after we broke up?

Maybe he was into her when he was still in a relationship with you and broke up with you to get together with her.

You are not with him anymore, it’s a waste of time mulling over something that has no effect on you whatsoever. I can understand how hurtful it must be, but it seems like he has moved on. You should too.

Maybe she was a shoulder to lean on after your breakup with him, and things between developed from there.

Or maybe there was something already there between them both when you were with him.

He was planning to break up with you, but you didn't know. It's all part of his plan.

If you're broken up its not your bussiness why.
