I was trying to find a number in my boyfriends phone and stumbled across someone listed as "the wife"...we've been together for almost 4yrs and have 2 kids and this is a recently added contact.

We've had problems with him talking to other women before and im furious.

I dont want to 'fly off the handle' but im losing it. How do I address this AGAIN...

Ive even thought about texting her from my phone but nobody likes getting a text saying "who is this" when they dont even know who it is from...

What do you ladies (or guys?) suggest?
