Just my quick take/guess.....
She "needs" to live with boyfriends...can't/won't support herself (she needs female roomates!
)
How much do you like her....do you want to ask her to move in with you? I predict that you will date for awhile, and if you don't ask her to live with you, she will find a new prospect, since she is so cute.
Are you two really hitting it off and falling madly in love and can't be apart...or might she just be using her love life to upgrade/maintain her living situation?
