Sex with girl who has a kid?

Ok so I have previously had sex with this chick who is 19 and she has a kid, told me after we had sex.  Anyway, I am horny and she is an easy lay.  She is a student at university as am I.

I have a feeling she is insane and I DO NOT WANT A RELATIONSHIP.

Yay or nay?

The first time I had sex with her I was very drunk.  I had 2 40ozs in me with nothing to eat all day.  I did not orgasm and neither did she.
