<< And another thing if your husband can't be all you need then you shouldn't be marry >>
Then the same should be true for men.
If your wives can't be all you need then you shouldn't marry! If you wives meet all your needs, then you don't need to look at other women, right? Not even soft core porn (sorry Cowbell).
Women generally have different needs from men. I don't have the need to look at half-nekkid pictures of beefy guys, but I do need to talk a lot and share my feelings/experiences.
I've been married for 8 years, have 3 kids, and seen it all.
A strong marriage can withstand many things, including this...
Besides, Frogger didn't give any details. How do we know what is really going on? For all we know, he is not a very good husband. We can't pass judgement on either of them.
My original advice still stands.
Behave YOURSELF properly... behave in a way that makes your mate WANT to stay... and then you have much less to worry about.
If you are a good, loving mate and your spouse STILL strays, then you can rest assured there was something wrong with your spouse and not you.
In religious terms, we called it Walking Blamelessly.
edit: Bobtist, sorry to hear that. Has she ever had counseling? Sounds like she's stuck in a really destructive pattern.
