To start off, YOU AREN' MARRIED, so you AREN'T RESPONSIBLE for his medical expenses or any of his bills.

I have many medical bills that ended up going to collection many many many years ago & that is where they sat. Hospitals have some funds to cover people who have no money but that's something HE needs to deal with the hospital about that. Unless you have a paper that he signs that they can talk to you about his financial situation, the hospital won't even deal with you......but if he doesn't deal with them, they will definitely try to collect.....but if he does deal with them, & gives them his financial situation, they will be able to either write off what isn't covered by medicaid (or whatever) since I doubt that he can make any small amount of payments & it shouldn't even come down to whether you can or can't because YOU ARE NOT MARRIED. His financial situation in the hospital should be all about what he can or can't afford & the hospital needs to deal with that situation ONLY.

My hospital situation happened because my husband said he would take care of it....they told him he couldn't because he wasn't me & he didn't ask them what he needed to do in order to take care of the responsibility.....so he just blew it off & everything went to collection.

I can see why you have strongly been urged to leave this relationship.....I think that would be in your best interest & your best mental health
