Do you realize that there are other implications to being married besides getting your BFF more aid? Like you being on the hook for his credit card debt ? What happens if he decides he doesn’t want a divorce in a few years and instead of the $750 “do it yourself” divorce you are planning you have to pay a lawyer? What happens if a relative dies and leaves you money and your “husband” claims it’s half his?
I see a lot of legal bills in your future.
