I am extremely concerned for your safety.

Since he is a cop, you will have to have ALL of your bases covered.

Meaning----if he tries to get you committed, it may indeed happen because he is the cop and you are the mentally ill person. That is, he will be believed before you are.

It is indeed a sign of abuse for a partner to threaten you if you mention ending the relationship.

He's saying....

"If you leave me, I will have you committed."

"If you leave me, I will make your life miserable."

This is not acceptable behavior.

I strongly urge you to create an exit plan. Save up as much money as you can. Get as much support as you can from friends and family.

Are you seeing an individual counselor?
