Lotus,
Your story reminds me so much of a story I was heard from my youth pastor (long time ago). He shared how he had a friend (I think he was even a pastor) who decided to go to Stanford U. and ended up "finding himself" which meant leaving his wife and I think having an affair too.
I'm all for education, but I beleive that a great deal of higher education is very, very humanistic and is not pro-family or pro-values and traditions, unfortunately.
I am sorry that your wife is suddenly into this "self-discovery" at the expense of your marriage. There is such a HUGE emphasis nowadays on finding oneself, loving oneself, all of that. We never hear about "denying oneself" like the Bible teaches, and often in "finding" ourselves, we are actually not finding life but the opposite.
I am assuming you are a Christian? I'm not sure, but you mentioned your wife's religious beliefs. There are two great marriage websites I'd encourage you to visit:
www.restorem.org and
www.rejoiceministries.org Both are marriage reconciliation sites. Read their testimonies and the testimonies of others. If you can, get the book for men at the restore ministries site and also get a prayer partner. At the other site, sign up for the free email devotional. It's called "Charlyne Cares." Both sits are extremely supportive of marriage and reconciling struggling marriages.
Also, there are two good books I'd recommend. One is called "How to Save Your Marriage Alone" by Ed Wheat. The other is "How to Win Your Wife Back Before It is Too Late" by Gary Smalley. You can order them through Amazon.com or your bookstore might have them. Both are very good.
Your post also reminded me of a chapter in a book by James Dobson called "Love Must Be Tough." He addresses "loving toughness" in various serious settings, such as adultery, abuse, alcoholism, etc. Well, he has one chapter called "Husband of a 'New Woman'." Which sounds like your situation.
It is pretty insightful. Here are some suggestions he gives:
"The 'new woman' needs space during her discontent, and it should be given to her. If she should separate from her family, let her go. If she doesn't call, leave her to her solitude. Let her feel that she is free, in the spirit that I have described [you aren't being mean but doing it in love... letting go with the understanding that you cannot control or force her to stay or to love you]. Open the door to her domestic cage, but make
her do the flying. As a responsible and faithful husband in this context, I would not voluntarily leave the family to accomodate her. If she obtains a court order to force my departure, then the responsibility rests on her shoulders."
Of course, he adds (and I do too) to pray. Prayer is powerful. God can use this time to help you to grow and He can make your marriage stronger through this. But, I'm sure it won't be easy, and of course, the outcome is unknown. You can't control your wife or her choices, and so in a way, you must "bear" with her and be strong and act in wisdom right now.
From reading your post, where she asks "Is the old me worth getting back," etc... I think she is probably confused. She is hearing these things at school and maybe about how life is supposed to be... the ideal of having it all and seeing the world, etc. But she is also a married woman.
I would encourage you right now to be her friend. Listen to her, bear with her, empathize wiht her when she is feeling stressed and confused. Try to deny your own self by supporting her and hearing her and letting her go through this time. Be her friend, be her friend. This is the part in the vows where it says, "for worse!"
I would encourage you again to go to those sites simply so that you can have some support and hope. And maybe you can get the James Dobson book too...you might check the library.
God bless and I do believe there is much hope for your marriage!!
In the Bible it talks about how we find life when we "lose" it. When we deny ourselves through sacrifice and bearing with others and carrying each other's burdens, etc.... we end up finding life. "To give is to receive." Your wife has heard many worldy ideaologies that teach the exact opposite. Understand this and pray with her, love her, and find your strength in Christ.
God bless.
