I [24M] had been text messaging a girl [23F] for a few weeks after she insisted multiple times that we get together sometime, When I finally asked her out she canceled last minute and said her kid was in trouble so she had to go to school to sort it out. We had been friendly for the better part of a year and I usually saw her once a week when I went to the restaurant where she worked. I would usually grab a coffee for anyone that worked there that wanted one, mostly just her, and occasionally eat lunch there and talk to her if she was working or grab a sandwich before heading to work if I had something scheduled. 

A few weeks ago she complained that she had kicked out her on again off again boyfriend whom she hadn't ever mentioned when we spoke, and that some really awful things had been going on in her life and that she was afraid she wasn't going to make rent because of not being able to work full time and not having gotten any assistance from him.

I told her that I could help out if she **really** needed it but didn't hear anything for a few days. That was when she messaged me on social media saying that her phone was shut off and that she really needed money by the end of the week to pay her back-rent to her landlord by Friday night. I took some money ($1k USD) out of my bank account, and told her I had it but had to work but after messaging that I was done at work she said that she was having her family over and didn't want to head out that night to get it, On Friday I messaged her and asked to see her (to talk about a budget/finances but also to give her the money) but she claimed to be busy working. 

I was a little suspicious because when I tried to call her it went to voicemail and not the standard "this line is deactivated" message, so I called her from a phone at work and she picked up (at which point I hung up without saying anything) and when I tried to call from my number it again went straight to voicemail. She hasn't messaged me and I haven't messaged her back since then (its been about 3 weeks) but I have been back every week to the restaurant but she hasn't worked the shift that I go to since then either.

AITA for not helping someone you caught lying to you after already having offered to help?
