I found out in December that my husband had been talking to a old girlfriend

I was married for 27 years to the love of my life. I found out in December that my husband had been talking to a old girlfriend and they were having an affair with her.

She also was married for 20 years. He moved out and now is living with his whore. I had his children and always was a good wife. I don't understand how he just stopped loving me.

He still wants to keep the physical part of our marriage going. I still love him and know he still loves me. This is all so confusing and painful. I don't know how to move on after this
