I'm so sorry you're in this situation.
To your question - in theory, ANYTHING can happen. What is likely to happen is another story.
I think for starters, you need to consider
1. what the standards are in your state (I believe some states start w/the assumption of 50/50 custody and work from there)
2. What would you & your husband want? My X never had any serious interest in physical custody (though he used it as a threat), but I was never really concerned.
3. You say he is abusive - is that documented? Has he been abusive to the children?
4. How old are the kids? I believe that generally, joint physical custody is less likely to be imposed on very young children/babies, BUT I'm not sure.
5. Is your mental illness incapacitating to the point where you cannot care for your kids full-time/long term without another adult around? Or could your X make an argument to that effect, even if you think (or know) it's untrue?
6. As for co-sleeping, I don't see why that has to come up. If someone says don't co-sleep, get a bed for the kids. If they wander around at night (and what kid doesn't) and crawl in with you...well... No vaxing is something I think some parents have had to compromise on in nasty custody battles. I'm not sure what you mean by metaphysics in this context.
7. If you're going into anything but the most amicable divorce in the history of man, you should have some legal counsel. Legal aid, maybe a law student clinic, something. Also, if there's going to be a battle for custody, I think appearances - both literal appearance (looking professional, conservative, put-together) and behavioral appearance (seeming calm, rational, thoughtful) can have a significant influence on how one is perceived. Another mama here says to always be the bigger person (I'm paraphrasing and I can't remember who it is) and to stay above the fray. ALWAYS be the good mom who is willing to do the best for her kids even if it's not the most fun for her.
