Relationship with a guy?

If the guy only wanted to hook up with a girl and he was actively meeting other girls or sleeping with them after she refused, but after getting to know the girl after 2 years, he decided to be with her.

Would he accept a guy like this for a relationship?

So, if this dude was all about hooking up and messing around with other girls when she said no, but then suddenly had a change of heart and got to know her over two whole years, well, anything can happen! I mean, if he's really shown a genuine transformation, then maybe he'd be open to giving it a shot in a relationship with her. It all depends on how much trust and communication they have, ya know?
