My friend keeps borrowing money?

So this is two part question. Am I being an asshole because I dont want to keep lending my friend money? She seems to always ask me for money as soon as my check it deposited. She takes a month to pay it back each time. I get it her and her boyfriend basically just bought a house and they have a lot of kids but why is she constantly asking me for money? And its gotten to the point she doesn't even ask me she just send the cash app request as if im suppose to just pay it like a bill. Then when she does pay me back she refuses to send it the way she got it. Should I ask her to send the money back through cash app and not through something I dont have?
