AITA For Continuing to Ask My Friend to Pay Me Back?

Throwaway because i don’t want anyone who knows me to come across this.

I (21F) have a friend, (27F), she asked me to borrow money a week ago, said she’d pay me back in two days. I said sure, because I’m a pushover and I don’t know how to tell people no lol. Anyways, I gave her the money, it was about $50 USD, she told me she needed it for pet food and gas money. I was cool with it. She’s always been a trustworthy friend to me, and I felt I could trust her with this.

Once the day she said she would give me the money rolls around, I waited, trying to see when she’d pay me back. But she didn’t. So I asked her the next day if she could please pay me back. I’m not rolling in money. I only gave it to her because I trusted her and she PROMISED to pay me back. She told me she would get it to me by the end of the day. I said okay and left it alone. I didn’t want to seem like the type of person who only wanted to get my money back. She still hasn’t given it back. And I’m still wondering if she will.

I kept asking her until now, and some of our mutual friends are telling me that I should know she’s struggling, and continuing to hound her about money isn’t being a good friend. That I’m an asshole because I seemingly only care about money. But I’m not swimming in money either. I need that money back. I made her aware of this when I gave her the money, that just because I have it now to give her, doesn’t mean I don’t need it back. And she promised me.

So, AITA for asking her for my money back?
