Do what you want/need for you. Since you don't have children (thank heavens) it can and should be all about you and what will make you happiest.
I wish I were in your situation. I'd run (not walk) away from this dolt and never look back. That's me, of course. That's why none of us can possibly give advice. Only you can meet your needs. We can't and neither can she. Only you know what you really want.
Come to facebook, baby.
