Serious family court help?

My boyfriend lives in Nassau County and his daughter lives in Texas with the mother the hasn't seen her for a year and he also please child support, she is 3 and due to a recent incident with her bf (he was looking through her phone and my bf texted to talk to the baby and he got all mad and start cursing my bf out...mind you she cheated on my bf with him twice, this is why they aren't together anymore) anyways the situation is like this, she's all my at my bf and she told him not to text her anymore (mind you that is the only way he gets to talk to his child b/c she hasn't learned to use the phone yet) it's been a week now, and he is all depressed about it.

My question is this: idk much about family court, but I have call the number to the Nassau County Family Court and they have been giving me the run-a-round for an hour. So I would like to know how can he obtain visitation right to his child b/c he is always going to Texas to see his daughter, and he has family up here that want to see her too.

What are the steps for him to get it?

Thank you!
