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? 

Nice try FailCreams but it is all too obvious.

To OP cut off your balls as I did and assume the role of the opposite sex as I have been doing for 13 years now.
