AIO for not wanting to buy my pregnant girlfriend a house just yet?

A little bit of back story:

I 22M don’t want to buy my 32F girlfriend a house just yet. She has outstanding debt over being sued which is why we are not qualified to get the house. She wants me to co-sign a loan to pay off her debt, and I know she won’t pay the loan because she hasn’t made any payments on the debt she’s had for almost 5 years. To me it just feels like I’m getting played.

I think she could possibly be cheating and she is pregnant I’m not 100% it’s my child which makes me want to get a house with her even less. For details about this check my other recent post on this sub.
