Input: To start this out my girlfriend and her two kids live with me. I don't have a problem with paying for things here and there. I do make a lot more money than her. But im not rich and i have plans for the money like bills and retirement funds.  she doesn't make a lot through out the year so taxes are a huge windfall for her. 

4 months ago her car breaks down and it has been nothing but a problem since she got it. leaking oil, randomly not starting, requires premium (somehow they didn't know this when they bought it) etc etc. and more the car was going to cost more to fix(full engine replacement) than it was worth. so we sat down and discussed it and opted to look at a new car. i would feel comfortable with her in a new car with the kids since i didn't want them stranded on the road in the middle of winter. 

anyway we looked around and found a car she wanted but she didn't have money to put down so i moved some things around and was able to put $1750 down for her on the agreement she would pay me back with her tax returns. 

tax returns come (8k) and she doesn't say anything so i give it a couple days then ask her about it. she gets mad because if we were married she says she wouldn't have to pay me back. she also says she has plans to spend it most of it and is putting 1k in savings and doesn't want to give it to me because she doesn't want to feel broke all the time. 

AITA for expecting my gf to keep her word? or feeling like she literally stole from me?
