Im 19 too I know the situation he is in..
you wanna know the reason why he cant do it when hes older? Cuz its a stupid fuckin thing to do now ! lol and when your older your not young and stupid..
NO girl is worth moving and living with after you have known them for 2 days.. period..
If you believe it will be that easy to get started and move in with her then go and do it bud.. If your life is shit and u wanna start over some where else then no better chance then to start now.. Moving to a whole new place ESPECIALLY just because you met some new girl 2 days ago is wack guy, and if she asked you to move in after knowing her for 2 days.. shes just a dirt bag anywayno offence... Show me where u met these girls after 2 days that ask you to move in and Ill move there hahah..
My 2 cents!
