Search Results: ex asked me for money

I thought she was a nice girl but when I started to hang out with her more, she has been rude, selfish a bit not all the time, she treated her guy friend like crap SO MANY TIMES and takes advantage of him because he has a car and money (he has a job). He's forgiven her so many times and one time she blamed him for "making" her go to the mall when she has a bad headache, but SHE chose to go. She starter hiting and pouncing on him and he called her out by telling her he's going to call the police if she didn't stop. Eventually she stopped and apologize. Also she took advantage of me for money. She knows I'm on disability and one time she asked me if I can bring $100 or $150 and I told her no I can't afford to do that. She would tell me to bring $40 or $50 to go shopping and out. She took my money and put it in her purse to "keep it safe." I tried to take it back but she hit my hand and told me to "back off". I felt like such a coward. Some incident happened and we haven't spoken in 8 months. Our other best friend told me three months ago that my ex friend wanted me to talk to her and there was a misunderstanding and her guy friend lied to both of us about some things. My ex friend apologized and I told her I'm glad she apologized. Our other best friend wanted us three amigas to reunite and hang out. She had to cancel because of a family emergency. She doesn't know this girl took advantage of me but she knows about her taking advantage of her guy friend issue.
My dad suggested me to not hang with that girl anymore and forbidden me to go to her house or hang with her. I know that sounded childish but ita my choice. Plus I don't wanna gang with her anyways. I have a job now and if that girl was still on my life, she would have taken advantage of me and ask for my paycheck. Hell no!

One of my best friends lives like a half hour away from where I m at and she asked if she can borrow $10 for me and I would have to send it in the mail since her date is this Saturday. She told me she ll pay me back when she can. We both can t drive. I know how to take the bus but it s too far to travel.
She s looking for a job though. Now I'm having second thoughts because I just went through a ex friend that took advantage of me for money but I know my best friend would NEVER take advantage of me. I don't wanna lie to her and say I can't send it to her. If I can't send it, what should I tell her?
