@Usernamehere,
I really despise it when people use terms like love and infatuation interchangeably. They're actually different concepts.
Infatuation = someone is attracted to you
Love = someone has deep feelings for you that go beyond attraction and could conceivably become a lifetime commitment
If it's love, then it's durable and stable and it doesn't go away when you have a tiny disagreement. When it's infatuation, that's a lot more likely to happen.
Only this woman knows what she would do, so why not ask her?
Oh, and please stop referring to grown women as girls. It's demeaning.
