Choke Hold

It's a somewhat long story that I don't care to type, so I'll just give you the highlights:

I haven't seen my kids in 13 months.
My ex called to say she would be flying back to the US to visit her terminally ill mother.
She asked if I wanted to pick up the kids for a few weeks.
I said yes.
The day before I was supposed to leave my ex called to say she didn't want me taking them.
Argument back and forth.
Worked Tuesday night till Wednesday morning, got in my car and drove to Omaha, Nebraska.
Couldn't find my ex, she wouldn't return my calls.
Drove back to Wisconsin without my kids.
She stood me up.

As you would imagine, I'm very angry at the moment.
