These are some of the biggest decisions you will be making in your life. No need to rush into anything until you are 100% certain you are making the right decisions for the right reasons.
How important is your relationship with your children? Would you die to protect them? If so, you should do everything in your power to ensure you are actively involved in their lives. Week on/week off parenting arrangements is the goal. Younger kids might needs frequent contact with both parents. 365/2 = 183. I stayed in the marital house until I had an agreement for 50/50 parenting.
You rolling over like a puppy dog is not in your kids best interest. You will have a lot of pressure from W,the legal system and who knows what else. You can handle it.
Strong and resolved. Control your emotions. Do not let them control you. Let W be as angry as she needs to be. "You look angry. We can continue this when you have calmed down."
Look into a fathers advocates group in your area.
