I think there just isn't a blanket answer. some guys get into relatiosnhips despite not being over ex's some will wait. some will get into a relationship and call it off because they realize they aren't over their ex...some won't, they may not be aware or the may not care that they aren't over their ex.
I think if you have a specific scenario in mind we might be able to better provide a more specific answer. but in this general form I think I'd say some will some won't
Most Helpful Girl
Yes, had it happen to me with some guy like 6 months ago. I felt really bad for him, honestly. And love takes time. Lust, infatuation, passion etc doesn't. Imo, the more passionate he seems (especially since it's new, c'mon) indicates just how hard he's trying to forget the last girl. Or...he could just be saying that because he feels bad in saying he wants to see/bed other girls and says he's trying to get get over some supposed ex so he won't be slapped. In which case, the best thing that could happen would be for things to fall apart because no respectable person would waste their energy or be seen around a (man) whore.
