honestly, what i found is when your looking for real advice, these public forums aren't the best place at all. not being mean or sarcastic, i've posted real questions before and was really stressed out and really just got annoyed and frustrated.
Now my advice may be completely pointless since I live in Texas (the heart of the bible belt) and is known to give a father no rights at all pretty much. all i can offer is my opinion and hope it kinda helps you some.
I would try to document everything he does thats benefical to the case. the fact he works 14 hours a day, get a paternity test if you can find the baby, and any all documentation that this woman wasn't exactly stable helps so much!!! if there are any first hand witnesses to her behavior (close friends, babysitters, church members) now is the time to call them and get notarized statements from each, the more the better!! even if they argued in front of a neighbor and she got just a little bit out of hand, GET A NOTARAZIED STATMENT FROM THAT NEIGHBOR!! And tell him to keep a tape a recorder on him all times, just in case for some reason she tries to reach him he needs to record everything she says!
And i do agree that there is "his" side, "her" side, and in between is the truth. but there's a child in the middle, and apparently this isn't the first time this has happened with her. and i really hate to break it to everyone, but i have experienced this first hand, a woman will use the fact she's "just a tiny defenseless woman" to her advantage and go to extremes to make herself look hurt and defenseless against that big ole mean man. even if it means going to a shelter and being fed and clothed for free for no reason in the world.
I don't know the circumstances, but because of my upbringing and the abuse i've survived at the hands of a "poor defenseless little woman" i am a huge advocate of fathers rights in Texas (which is pretty much non-existant) I wish you all the luck and hope the best for the most important party in this unfortunate situation: THE CHILD!
