Stop in for a cup of coffee

I just screwed up today I think. I love my niece to death. And she got married about 6 months ago. They are both in the Military except he is Army she is Air force. She is in New Jersey close to Philly in Air Med. He is Fort Drum in New York. Long story short. Because they neither have credit established and they (she) needed a good vehicle and I co signed. Man what was I thinking.
