Hi little sister heres some Big Sister 63 advice; dont take in any more friends for fear of them being on the street nor lend them large amounts of money if you value keeping their friendship. From my experience, it is the surest way to end a life long friendship. Our expectations of them doing the right thing are two different things; especially when one is down on there luck. I learnt when you give; you give and do not expect something in return, but up to a certain point! Cause Im not a financial institution, nor a Saint. HA!
In this case, when you open your home to someone it does not mean you and your boyfriend forget setting some ground rules; that is a contribution to the household and expect the other person to wake up and think of it themselves, 4 months later!? If you are laid-back about these things, don’t get angry with her as she is only doing it because you guys have let her. Its no ones fault when you learn about these things.
To my thinking, 6 months is most generous of you and more than enough time to endure a third person. So for the next two months if you want to keep this friendship; Id be saying, hey friend it looks like we need a bit of financial help from you towards the gas each week, and if you wouldnt mind providing all your own food and transport to work from own on before you go, it would greatly help us out. If her answer is agreeable to this, you have a friend for life. If not you have a hic-up that requires you to be firm without blaming anyone, Im sorry friend but we are not in a good financial position anymore; and Im sorry but we need you to seriously look for another place within two weeks. Again its up to her, two months or two weeks, simple.
