love sux...

[CD5Passion]

me and my girlfriend have been dating for nearly 5 months..not long but for 3 months before that we were genuinly best of friends and we actually were saying "I love you" 3 weeks before we decided to date.
I love this girl and I know she loves me but the past week things have been weird, she says she never had time to be single much in her life and she kind of wants that, but then she says that she wants me and loves me more than she's ever loved anyone and would never want to see me with another girl ever
We have a incredibly strong relationship and we never fought cept for once the past week. If we were to break up it is definate that we would remain closest friends and all I want is for her to be happy because I would give my life for her...I'm so confused what do I do?
