Help me get my sex drive back!

My sex drive has been so low, and I believe it stems from the below situation.

I’m 5 years out of a mentally and emotionally abusive relationship. Sometimes physical but that was rare. I went from being outgoing, fearless, and fairly confident to being scared. After I finally got the guts to break things off with him, (I was scared and he was living with me) he threatened to kill me but that was ultimately all it ever was.

Before him I had a high sex drive, the man I was with before we would go at it everyday, sometimes multiple times a day. But when I got with my abuser it tanked very fast.

I’m now married to the guy before my abuser. (Perfect man. Mostly perfect relationship we both just needed some time apart to grow separately) but even after 5 years I have no sex drive. I still find myself thinking of myself the way my ex made me feel. And I know my husband has a high sex drive, and I feel like a shit wife for not feeling the same. I want to be better for him, I want it. But I have no idea how to fix this.

Any help would be greatly appreciated!
