Hi MPVG,
Only a doctor can say for sure, but the symptoms you've described do fit what I understand about bipolar disorder. (

Folks with bipolar disorder, like folks with schizophrenia, sometimes aren't able to recognize that they're ill. I agree it's a good idea to call the suicide line - most suicide lines are just as much to help people concerned about someone suicidal as for the person themselves, so don't feel awkward about calling.
Since you're in Ontario, I suggest you also contact the mood disorders association of Ontario:
http://www.mooddisorders.on.ca/ who might also have some suggestions.
Above all it's important to look after yourself and your kids. If your finances are merged with his, you may want to un-merge them or have some money of your own that he can't access. If he's yelling and pressuring you for sex you don't want, you might look at whether you need to live apart till he's more stable. The kids will need to know it's not their fault, and that they can rely on you to be the adult.
Good for you for reaching out to his parents. This is not something you need to cope with alone.
The good news is that the treatments for bipolar disorder (if that's what is going on) can be very effective.
I hope you will keep checking in with us and that your meeting this weekend goes well.
Welcome to the group.
Sincerely,
Sophia
