My Ex-Wife Won't Let Me See Our Child - What Should I Do

My question involves a child custody case from the State of: Florida

My x-wife and I share our son 50/50 per our divorce agreement. Every time she gets angry she says she is not going to let me see him. So far they have been empty threats, however this time I think she maybe for real. I told her I am getting married and she flipped. What should I do if my son is not at the school on Friday when I normally pick him up? Or if she is there and tries to take him? I don't want to make a seen in front of my kid and I'm not sure what the best move is?

If she withholds your court-ordered time, you can file a motion for contempt.
