She would be great for unprotected sex cause cant get pregnant. But instead of paying her bill you could aswell get yourself a slut for that money.
Anyway forget about girl if shes distant. You dont own her anything and she should be yours after all that you done for her. Really man safe yourself a trouble. If after meeting a girl she goes distant then its not the real girl for you. It was cool chatting but relationship cant take reallity. It will just get worse after every meeting.
I understand you have troubles but choosing troubled girls is not the way unless you want to get into more trouble. There are better girls, just keep searching and talk with good looking girls on a street and in shops if you can man up. It will be much better than in internet.
Doubt kills more dreams than failure ever will
