@farmer2247,
You made a vow so stick with it. You married your wife and made a promise to her, your families and the community that youi would stick with her and love her and work out differences.
For the moment things are little troubling with your wife so you want to bale now 'cause thing's are a little hard? Or just because you and your ex are fantasizing a bit in your idle times?
Do you really want to ruin your wife's life and her trust, too? What about the impact on her, her and your families (kids..and parents) etc?
The grass is always greener in the other yard.
Stop fantasizing and work out your differences with your wife. Marriage is an important step in your maturation. It can be hard work! There's some
'heavy lifting' at times. Who says that after awhile you won't come up to the same problems with your former g/f? After all, she has made some serious errors, as well.
I don't see any evidence of your stating that you're miserable or there's irreconcilable differences. Are there any? Distance can be overcome with some heartfelt conversations. When waas the last time you had a heart-to-heart convo with her?
