I'm inclined to agree with Anvil. Even with the pregnancy, what is the purpose of you being available for her 'complaint of the day?' It's unhealthy for you and typical alcoholic quacking on her part.
I understand the need to stay aware of her pregnancy, though. Since there's not much you can control until custody proceedings are an option, is there a way you can be notified by family or a friends of hers when she does have the baby?
I guess I'm thinking the healthier you can get in your recovery and the less affect she has on that between now and then, the better you will be able to take on the responsiblity of that child and deal with her once that happens.
If she's not drinking while pregnant, which I may doubt as well, the stress of having a newborn may trigger her to drink after the birth. I would want to swoop in and grab that baby, too!
Hang in there, Ives. We can endure almost anything in the short term. Focus on the future!
Hugs,
