I'm depressed, my husband is in Florida to visit his daughter and the ex is driving them around.?

Long story short the Ex wont let her daughter travel to our home in our state. I wanted to go to Florida with him and he said no. He wanted to spend time with his daughter alone. To save a dollar he is not renting a car and going everywhere, letting the Ex take them. They went to see alligators, to the beach , to lunch. He keeps on calling me up and telling me how great things are. I can't take it anymore! I need advise.
