Where should I propose Me and my girl have been dating for two years I think it's time to propose when and where should I do it?

Let's see what you've posted. You have autism, you are married but aren't having sex, you don't know HOW to have sex and need step by step instructions, you have a non-verbal daughter as well as a 13-year old son, you are 22 (or 24, you can't decide), you have a job coach but things are not going well and on and on and on.

I'd print out all of your questions and hand them to her. She'll figure out the question.

I'd do it during group therapy, based on your other questions.

Or you and the wife you're always posting about could invite her for dinner and you could ask her then.

Marriage is a social contract.

Use your imagination. You know her better than i do (at least i hope so?)
