Hey pale...
Sounds like you will be going through the big D soon enough.
I woke up the same age as you and had two kids who were very young. That was 9 years ago for me. I can tell you there is hope and definitely light at the end of the tunnel. From my experience you don't need to be uber aggressive and forbid all things jdub and go nuclear on family or soon to be ex w/ lawsuits. Your first priority is your child now, not your ex. You will gain friends by getting your kid into girl scouts, soccer camps and all the other school things you will be involved in with your daughter.
You mentioned that wife calls you and has you take the kids... awesome... take them whenever you can. If and when you do go through the divorce go for at least 50/50 custody (decision making) and 50/50 placement (where the child will live) The court system wants your children to have as much time as possible with both parents. What the court does not want to hear (in my experience) is all the crazy beliefs that the jw mother has. (None of my judges thought when push comes to shove that the mother would let our children die because of the blood issue) If you personally cannot keep the child at your residence for 50/50 placement... get at least 50/50 custody and tailor the placement schedule to your schedule (with the caveat that when circumstances change you can go for 50/50 placement)
I have gone with and without a lawyer. I have had mixed results with both. Be involved is my best advise as far as a lawyer goes. Push for the home study with your county family court counselor. That person will be your childs advocate. Explain to that person all the experiences and opportunities you want to give them and what they will miss out on when they are with their mother.
Hit me up anytime, my experience with court is pretty extensive although I have not won everything. My decision to leave was well worth it. My girls are well on their way to being out!
