Wedding Bells Are Vibrating

I've been engaged to a girl for two years. For about two weeks, she's been texting a sales guy she met through work, and the text messages are in the hundreds per day. I found out from our cell phone bill, then snooped on her phone. Last night when we were out, I read one when she went to the bathroom. It said "Want 2 go out of town w/me?" I didn't see her response because I spotted her coming back and quickly returned her phone to her side of the table. She hasn't been neglecting me lately; if anything, she's been a little more loving. So, am I wrong for being suspicious? If not, how do I approach this without being a jerk in case nothing's going on?

--Unsettled

There are days when a guy needs to text a girl 15 or 20 times an hour -- typically because he's her gay best friend and it would mean so much to him to have her there the first time he gets his eyebrows string-plucked. But, hundreds of messages a day? Assuming she works an eight-hour day, if she sends 200 texts during her work day, that's 25 per hour, which means she's texting the guy every 2.4 minutes. So, while there's some tiny, electron-microscopic chance she isn't cheating on you or about to, it's clear she's screwing her boss bigtime. And, come on, you're a straight guy. Is there a girl in the world you have that much to say to -- unless you're scheming her into bed? And then, while I can't get behind snooping, when you did snoop, the one message you saw was "Want 2 go out of town w/me?" Whaddya wanna bet his follow-up wasn't "Oh, N where R my manners? B sure 2 invite ur fiance!"? A girl who's serious enough about a guy to be engaged to him will make it clear to other guys that she's off-limits; usually by starting sentences with "My boyfriend and I," and long before some sales dude starts sending her sonnets about her breasts with all the vowels missing. Beyond that, being in a relationship with somebody, especially when you're on the verge of making it a lifelong deal, means you put them first. Sure, you have friends of your own and stuff you do without your partner, but if you're committing to one man, there's something a little off if, during sex, you're tempted to excuse yourself to the bathroom to see if you have any text messages from another. Now, maybe this is just a last-ditch oats-sewing before she becomes Mrs. Cleaver II, or maybe she has cold feet and is too big a jerk to do the decent thing and call a time out. Then again, maybe she just wants what she wants when she wants it. If you start by accusing her of cheating, she's likely to deny it. Take a less confrontational approach -- over a week or two, so you both have time to think -- and discuss whether the two of you are really ready to get married, how you'll both stay monogamous, and, oh yeah, does she have any idea whose number that is on pages one through 326 of the cell phone bill?
