He has joint custody of 2 children from previous marriage and I believe he gets to claim one of them on his taxes.

The term “family” as used herein shall mean one or more persons related by blood, adoption, or marriage, living and cooking together as a single housekeeping unit, exclusive of  household servants or a number of persons, but not exceeding two (2) living and cooking together as a single housekeeping unit though not related by blood, adoption or marriage. 

Yes, you love him, but that does not obligate you to take care of him in old age nor figure out how to manage his dementia, which is a medical condition that needs the proper attention, nor risk your marriage or family finances to "help him out."

@Theresa Harris The new restrictions state that the home must only be used as a "single family" home, defined in their terms as either an individual or a group of individuals related by blood, marriage, adoption, fostering, civil union, domestic partner, or other "parental or connubial relationship".

I was wondering how to protect my assets from marriage.

@Andrew AngererCongrats on your marriage
