14 years of marriage to my best friend

I discovered a week ago that my wife (age33) of 14 years was having an affair with a 22 year old. I am devastated. We have 2 kids 11 and 15. They are confused why she left. I told them she doesn't love me anymore and she wasn't happy. I asked her to move out. She did with a girlfriend.

The pain is unbearable. I have crying fits all day. Can barely function. Everyone says it will get better but I just don't see it. I still love her so much. It hurts her to see me like this but she has made her mind up. Now tomorrow I have to visit with family I haven't seen in 20 years.
