I think I'm done

[Little]

Addressing these out of order:

I don't feel like we've done everything we could do. I feel like our marriage is on life support and the doctor said there is a treatment that can give it 50% chance of survival, but H wants to pull the plug without trying that treatment.

I so know how this feels, and it [censored]. You are not alone; a lot of people give up when they should be fighting. And by 'fighting' I mean valuing their relationship and the person they love enough to give it all their effort and do what they can to save it.

Financially D makes all of the sense in the world.
Emotionally, I'm still not ready.

If you're not ready for a D, get back on the DB wagon. Start making your 180s and showing your H you can be the wife he needs you to be. Become someone only a fool would leave.

You can do this. You have the strength, you just need to commit to it and take it one day (or one hour....or one minute) at a time!

I'm rooting for you!
