Wynne - get a paternity test, and then sue for custody.
If you don't get the test, and the kids is not yours, the state doesn't care and will go after whomever is on the birth certificate for child support - might hear this referred to as "providing male".
If the kid is confirmed to be yours, you're going to have to sue for custody.
You're not going to be able to do the test until the kids is born though, so maybe just give her some space for a moment, it could be her freaking out about being pregnant. Don't let her burn bridges. I'd definitely say "okay, i will" next time the paternity test is brought up, and see how she reacts.
Sorry to hear that but this seems right on point. She is pregnant so don't trust the moods. It can be a difficult tone for any relationship. Sounds like you have more invested in your 'family' than she does. It fricken sucks. I used to think that going half on a baby was even an option. Nope. I see my 'brother in law' get dragged thru too much shit just for a kid and some ass.
I used to tell this girl if neither of us were married by 35,I was okay with that. I want too go slap the shit out of myself for even thinking like that.
I talked to my mother last night after everything went down and that was her advice as well. She was telling me that my gf could be playing hardball because in the case that the baby isn't mine, she isn't going to come after me for child support knowing that I going to get a paternity test ASAP to prove if I'm the actual father. I would love to sue for custody, but being as she is in the military and currently testing to become an E-5 in the Air Force while I'm just a college student using the GI Bill to get my Computer Science degree, that's going to look better to a judge that she takes care of the baby. I didn't sleep well last night over all of this. The baby is due in December. Gotta get my weight up for my child now.
