More stress...

I received a phone call from my ex who took our son to Six Flags this weekend and I was shocked to discover he's sick again. My son is stuck 3 hours away with a guy who should be in a hospitial and here I am at night unable to go save the day.

I'll have my sister go in the am to get him if he is unable to make it home himself.

He's sick complaining he's poor and he's got my kid with him. I think he will probably make it home but I need to borrow some cash from my mother to get him to a doctor and get him med's. I could just kill him but that wouldn't be smart right?

I'm almost nine months pregnant and I'm more worried about him and his illness then having this baby I'm pregnant with. I guess deep down I feel like he has no one. He came to live with me and that I disappointed him and I have to keep saving him. Trust me if I made more I'd never ask him for a penny of child support but I don't have that luxury.
If I don't get him to the doctor he'll miss work and then he won't be able to give my kid a penny. Not that I've gotten one.
Why can't he see that having a family, people who love you is not the worst thing? If he was alone he'd be screwed stuck in a hotel room with my kid and he could be dead. He has no idea how much we all need family. I think if he does end up needing to be picked up I will try to reach his parents. He's ill, he's been in the hospitial and somehow they need to know.

My sister is of course upset, it feels like it's with me but she immediately offered to go and save him. I wish I could go but I can't. If I were to go into labor in the middle of nowhere what would we do?
I'm more worried about him and my kid then I could possibly be about myself. I know that if something happens to me that I'll have my family but if something happens to them?
I feel helpless and useless, if I had the cash and the body I'd be in Vacaville now.
Fingers crossed.
