What state are you in? Are you even in the US?

Anything GIFTED to you pre marriage is yours unless a pre nup states otherwise. In *some* cases if the engagement ring was a family heirloom it may have to be returned but that paperwork was long in place.

Who gives a rats ass what his attny says? I can support myself just fine as well but I still get two checks per month smile

As my attny used to say "extract the facts".
