You're not Facebook friends because you refer to yourself as the father of her daughter. That's probably how she refers to you as well, if she's even that polite about it.
Baby Momma probably knows, because you no doubt slip and brag about where else your not so sterile fingers and withered tongue have been. She's a mother now. Her home has to be free of varieties of bacteria. Clean up, don't be "yourself", memorize the child's name, and maybe you'll get to see the little one, if you give a shit about that. If you just want to do Mommy again, leave them alone. Let them find a nice guy. Unfortunately you'll find another undeserving girl and mess her life up too.
Duh!!!!
