Can you explain a little bit about how this timeshare would work? How can he afford to invest in this, if he has no income?

I think your fears for your daughters' welfare when they are with their dad are very, very well-founded. If I were you, I'ld be very glad that football season is keeping this guy away from your daughters. Start a journal and make notes on what he does, like showing up late to get them. Note down any episodes of drinking that you are aware of. If he is prone to drunkeness, I believe the court would be very sympathetic to limiting their dad's access to them. Like you, I would be scared out of my mind. And your younger girl does not need any destabilizing influence compounding her problems.

I'm glad you are finding that being away from your ex is allowing you to have less anxiety. That's a big confirmation that separating was a good move on your part.

This man is not interested in being inconvenienced by the respondibilities of fatherhood. But he's building a defence by saying you thwart his attempts to be involved with the girls. He plans to use that defence for many years. He thinks he's being clever and finding a way to keep people from seeing him for what he is - a negligent father.

Protect your children. No father is better than an irresponsible one.
