Please help.please advise!
Legal advice is not something you can obtain from a message board, and you didn't ask a question.
However he is threatening me that he is going to get a full physical custody of our child because he works from home, make more money than I do, lives in a fluent town,and a family nearby for support.
Those are all things that will work in his favor, but they're not dispositive.
I also live in a nice town.
Just FYI, subjective assessments of "nice" are largely meaningless.
He also told me that because I have been divorced before, it's going to look bad on me.
Nonsense. It's completely irrelevant, although the fact that you "have . . . sole physical custody of" your child from your first marriage could impact things.
I suggest you confer with a local divorce attorney.
