It doesn’t matter if you are male or female, the mom or the dad role…you may find yourself trying to co-parent with someone that you don’t see eye to eye with.
I’d love to say that there is an easy solution. I can waive my magic wand and your ex will be cooperative and work with you to make good decisions in the best interests of the kids…OR maybe it would be easier for me to just make a movie about it instead.
What people forget is that even if you were still together you and your ex would have disagreed about parenting issues. How you handled them would have been different though.
Without a vested interest in the relationship there is little room for open discussion and compromise.
