I can't stand my wife anymore; should I stay or go?

"I found out my wife of 11 years cheated on me with some guy. This was last year June. She confessed to me after I confronted her with the facts. I decided to forgive her and stay married to her because I have cheated on her in the past too and I didn't want to destroy our family because we have four small children together. The thing now is; I don't love her anymore. I can't stand her and can't even bare to touch her. When she talks to me I get so angry I feel like stabbing her in the eye but I've never laid hands on her. I don't talk to her much except when we want to talk about the kids. We live in the same house but as strangers. She's really tried to make it up but it's not working. I actually hate it when she's around me, and haven't touched her since I found out about the cheating

I thought my anger and disgust at her would fade with time but it's been 9 months and I still feel this way. Will this anger ever go away or should I just end things with her
