I found out that my wife was emailing an old boyfriend on classmates.i then looked in her internet history?

First off, looking at old boyfriends on the internet isn't necessarily a red flag. Doesn't always mean she's going to go cheat. Sometimes it can be fun to go look at what has become of your exes, especially if your life is going well and theirs isn't. However the emailing thing is a bit different. What was the context of the emails? That's a clue here. If they were hey, how ya doing emails, then I'd still be upset, but not as much as oh hey baby, how ya doin? type emails.

She's looking for some excitement in the relationship. Why don't you go talk to her instead of us on here? Not talking to her won't accomplish anything.
