it is not 50/50. She lives 90 minutes away and they are in school. She has denied me days.definitely It is 100% up to her right now. I have no say.
You most certainly do have a say. You have to stand up for yourself. NO ONE CAN DO THIS BUT YOU.
You may have to move closer. It's not one hundred percent up to her. You request more time and make an attempt. If your denied, walk away don't get sucked into ANYTHING and then go file a police report (no need to make a scene, do this on your own afterwards) and see a lawyer ASAP!
