To sell my car or keep it...

So I'm about to go through a divorce, I found a trailer home that's been upgraded, the woman is selling for $40,000. Here is my dilemma.

My 2020 Chevy equinox is worth $27,000 I owe $33,000

I'm the only owner and have no accidents. I am under water so to speak. My monthly payment is $685.00 a month, my husband guilted me into buying it because at the time it was the only thing I had to pay for that took a big chunk of my paycheck. I'd like tell sell it, and get a used car, like a Chevy Trax that will cost $10,000-$13,000 and just carry over the rest (-$7,198.00) then hopefully I can have a smaller car payment. Is this worth it? Or should I stick with my car?
