1) This dude seems very insecure. Look, if she gon' cheat on you, she'll find a way, trip or no trip. You gotta trust your wife. If she does cheat on you, well, you decide what you are going to do about it then. You can't control your spouse and shouldn't try.
2) What, can't he take care of his own damn kids for a few days. This "makes me feel guilty about having young children and still wanting to go" - dude, everyone needs a break sometimes, no matter how much they love their kids.
Give her a break, be a dad and take care of your children for a few days or a week, whatever, and when she comes back, she'll be happier, less stressed, and probably missing you and the kids and ready to spend some quality time with her family.
Be a true partner, not a parasite who expects the woman to do everything and never get a break.
