Am I wrong for ending a 20 year marriage because I learned my wife cheated on me while we were dating?

That is the question of this poor man who's just found out some terrible news.

So, my wife and I, she is 44 and I am a 43-year-old man, have been married for 20 years.

We started dating in high school when I was a junior and she was a senior. We were long

distance for her first two years of college while I was in high school and did one year at community

college. Then we went to college in the same city for a year and we've lived together since. We got

married the summer after I graduated college. Our marriage has been pretty great so far, but I initiated a divorce after I discovered that

she was sleeping with multiple other men for the two years we were long distance.

Just after Christmas, we got together with a few friends of hers from college to catch up,

have dinner, hang out.

We talked about a lot of stuff stuff and my wife mentioned that we met

in high school. Not that we dated, just that we met. Her old college roommate commented that it was

crazy that we met in high school, had a few wild years in college, then ended up together.

I played along and commented that I didn't know if my wife was as crazy as I was.

The roommate started to tell a story, but my wife cut her off and said that she was uncomfortable

about it. I sensed that something was up, so I said that we actually started dating in high school

and were together for my wife's entire time at college. All of my wife's friends got real quiet and the

rest of the dinner was awkward. On the way out, one of her other roommates took me aside and said that

I should have an honest conversation about what happened at college. I asked my wife on the way

home and she kind of blew me off. I told her it was important that she was honest with me and again, she said it wasn't important.

When we got home, I told her I was going to stay at my brother's house until she was ready to talk about what happened in college.

The next day, she came over and admitted to sleeping with several men during her first two years at college.
