My boyfriend's sister (S) has two children and one on the way with her boyfriend (I shall call him R). R works as far as I know and gets paid fortnightly in his job. Many times in the past Ive been asked to lend money to them to buy things for the kids as they didn't have the money they needed. Yesterday my boyf (D) called me asking if I could pay £10 into his bank account (Im away from home at the mo) so they could get bread and milk for the kids as there was none in the house and they didn't have any money and S was 50 miles away visiting her mother (with the money). For some reason she didn't leave any money with them before she went. I couldn't say no as they are only 18 months and 2 and a half and they need food after all. Also I will be there Friday when D gets paid so I know I will get the money back.
Anyway today they started asking me to go to where they live (3 hours drive from me atm) and they were practically begging, and I knew something was up. They (R) was asking me to just get my housemate to hand in my final ever uni essay and get her to forge my signature on the cover sheet because they needed me to go tomorrow! Like I was gonna risk my whole degree at the last minute! Eventually it came out that they had only one nappy left for the baby! I gave them £10 yesterday and I cant understand why they didn't buy any nappies with the money they had then. It's bank holiday monday and I cant pay any money into the bank and even if I could, S is 50 miles from them with the bank card so they couldnt get it anyway! They asked their neighbour but she said she didn't have any money either, I dont know what's going on now either.
Anyway my problem is that Im hoping to be moving to the same city as them soon with D as we both like it better than our hometown. I don't want to become someone who they think they can run to when they need something they don't have the money for. when it comes to the kids I can't say no because theyre only babies and they need food and nappies and that. They seem to think I have a constant supply of money and think Im loaded (I wish, I have enough money to get home this week and that's it, not a pound more

Sorry that was so long...anyone got any ideas????
