My girlfriend asked me if i can co-sign a loan for her to help pay off her debt but I think I'm going to say no.
Is there a reason you are hesitant about co-signing a loan for her?
I'm not sure if she can pay back the money
Wanting to help your girlfriend is only natural but if she risks damaging good name or making your life harder by tacking on debt that she can't pay then you should definitely say no. Of course, we want to help the people we love but it should be expected that sometimes they're asking for too much.
I want to be a good boyfriend and help her.
I can understand how you feel. It is okay to want to protect your name from someone that might hurt it. A loan is a big deal and can ruin your credit if you can't pay it back.
