Divorced people of reddit, what was the final straw?

Probably too late but oh well here's mine - I found out my wife was spending time with a co worker on 11/30/15. Said it was just a friend. Caught her 2 more times at his house (told her not to, i wasn't comfortable, blah blah blah). She went home to her folks to get space and clear her head, never admitted and constantly denied having an affair. Came back and said on a Monday how she was going to go stay somewhere for a bit because being in the house with me made it harder. Found out she rented an apartment with the help of her parents and didn't want me to know where she was/what she was doing (i guess to keep me in the dark and have me as a plan b). She stayed at the house Monday and Tuesday and then just didn't show up on Wednesday and Thursday. On Tuesday night I had asked her if she wanted me to file for divorce and i would be the bad guy. She said she still had faith in our marriage. Found out she spent the night at her co worker's house on Wednesday and Thursday night and just like that we were getting a divorce.

I thought we were fine until 11/30/15 and then my whole world was just destroyed in about a month. She has a new apartment and jumped into a new relationship (found out they went to St. Thomas together recently.

But hey guess what, I've learned a lot from the experience and will be smarter in life as well as in my next relationship. Guessing she didn't learn too much since her family handled her divorce and helped her run away from her issues, and she didn't stop to look at what went wrong in her last relationship before jumping into a new one. I've heard the doctor is already cheating on her with another nurse in the hospital and she doesn't know about it. She's in a dead end relationship, and I've been having a great time enjoying my new life.
