Ex is not there for my kid.

Hello!

I have an 11 yr old daughter from my ex. He used to live in our state (il) and saw her usually every weekend. Last year, he decided to move to fl to be with his new girlfriend. He has only seen our daughter for maybe a week last fall when he came to il for her bday, maybe a week when he came back to see her for xmas, and then she went to visit him for 12 days last month. That's it. He doesn't call her (she doesn't have a phone so she only communicates through my phone when she wants to call him.) he only pays $400 a month for cs. I am struggling to understand how he could move to fl and leave his daughter here. He moved there in aug and only saw her in oct, dec and june. And who knows when he will see her again. How is this acceptable? How could someone decide to leave their child that far away to be with some new chick? Am i overreacting? What kind of man does that, and is okay just seeing/speaking to her whenever? Is this normal for a 42 year old man to be?
