I have no legal leg to stand on because we have not filed or have any legal separation agreement. She has offered that they can come over until bedtime then I have to bring them home. I am at her mercy on any and all decisions made regarding the kids. I don't want to start a fight but she is unwilling to discuss matters. Its basically her way or no way.
If you haven't filed for divorce and there's no separation agreement, then why are you at her mercy? She's being a bad @ss (aka a bully); you can do the same.
