I think you're right; it's a recipe for disaster.

I posted on here a little while back about a (married) male coworker I am friends with who is incredibly extroverted and whose natural extraversion tends to border on flirtation at times. I also talked about the fact that I've always had a crush on this guy. Never in a million years would I think it would be okay for us to start texting--mainly because I am a single female that his wife doesn't know, but also because of how I feel (I'm pretty sure his actions are just his personality).

This guy and I get along very well...within certain boundaries. So sure, someone in a relationship can have friends of the opposite gender. But from what I understand marriage is hard enough, why invite temptation by stepping out of bounds that you have to hide from your spouse? Especially when your marriage is going through a rough patch. From what I understand, a couple is to work hard to guard their relationship. I am loathe to blame the woman (because I feel like it's always the female being blamed when a man is toeing the line) and I don't believe it's all her, but if she had any respect, she'd step off. Texting about putting the kids to bed is the piddly stuff you text your BFF about, and she needs to find another female or single male to fill that role, not your husband.
