Then.i.came into the pic we.startd.as.friends n startd to.grow.but he.told he want.to.make it with her but.she.told him.he.had.to drop all his female friend but he.didnt. Even.though he didnt want a kid he stepped up.but.she.didnt.allow to be invovle out 9months he only went.to.1.doc app and she didnt even call him.to tell him she in labor she called him.after birth he.didnt give him his last name or sign the birth cerficate. Once again.he.said im try to make.it work she told she you.trying do for your son im not going.put you on child support to find 2week.later he.was served.with childsupport her xcuse .her.aunt did.it which turnd out to be a lie in the end. He wasnt even.allowed to visit his son without her being there and wasnt not allow.to.take any where. Finally he took her to court he got supervised visitation with her being.there.
