You obviously love your wife or you wouldn't be asking this question. Fight tooth and nail!!! Not with your fists, though. With your love. Persue her. Just as though you had never been married. Only, with the knowledge you have gained. She found something new and got INFATUATED with it. That is NOT love. She is the one who is confused! Grandma advises marriage counciling, and I advise Putting GOD right at the top of your marriage. He incorporated marriage from the beginning and noone in the entire universe will fight for you more passionately than GOD! I'm not being religious, as it may seem, I"ve actually been in your shoes, and your wife's shoes. Lining my life up with GOD'S word made the difference. My marriage still encounters hardships, but, nothing too hard to bare. This will most likely take a while, don't give up!!! My wife and I didn't give up on each other, we're closing in on our 18th anniversery (Dec. 21). And we added 2 more children for a total of 4!! She worth the fight!! And if you do choose to give up, you'll always wonder, "what if I had fought?" Don't wonder! Find out!!!
