How do I get over a mind controlling, y but bad for me Scorpio ex? ?

You have low self esteem. You did not "love" your Scorpio man. He did not "love" you. After all you've been through, put your physical lustings aside, take care of your child and get control of your future. You sound very immature and lost. This is a pattern you have allowed your life to take? Grow up. Or go back to your bed buddy and let him beat you senseless. If you do that, you're only getting what you deserve.
