That's rebounding and using someone else to get over or get back at you're ex. It's never good to date while still heartbroken over an ex cause your heart is still with them. It's also not fair to the other person cause they may truly have feelings for them but the feeling isn't mutual. It's basically wasting time3

nothing wrong with it, but expect internal conflict as you try and figure out your feelings about the new person and the old one.
maybe be honest with anyone you are starting a serious relationship with, but otherwise those feelings are yours and yours alone.0
