You have to sign your name to get a car loan...but, not to fuck and produce a child!!! That is WRONG! I don't give a shit about the OP. He gets what he deserves. The child...that is another story. This moron produces a child...but, has no commitment to the child or mother. And now he is here asking for reassurance...here is my reassurance...you committed nothing...expect nothing. If she is fucking around...what did you have in the "card" game? You had nothing...no commitment...thanks for playing...you should have married...then you could have said something...as of now...you know not whether she is getting better at sex via expansion of her own brain...or from new experiences fucking around...either way...you had no COMMITMENT IN THE PROCESS!!!
