Digitalos--
Did you ask your wife what led up to this? Is there something she wants from you that she is not getting?
Instead of heading straight for the jugular with divorce, maybe it would be better for you 2 to separate for a time and see if divorce is really what she wants. A separation will give her some time away--sounds like what she's after-- but it will still give you time to work on your marriage, hopefully to prevent the divorce.
No offence Digitalos, but you said you wanted a woman's perspective so I will give it to you straight.
Men are often clueless about what is really going on. There are times when I feel completely unloved, unappreciated and disrespected, and my husband will say to his friend "Everything was going great and suddenly she got upset with me for no reason." HA! There is always a reason.
The number 1 Rule of Marriage is this: Woman NEED to be loved by their husband -- more then they love themselves, more than they love their friends, more than they love their video games or hunting or car or WHATEVER! WOMEN WANT TO BE FIRST!!!
My husband will often ask me "What do you want from me woman!?" and my answer is ALWAYS the same. "I want you to LOVE me!"
For me that means talking, hugging, listening, asking me what I want, what I think, considering my feelings, speaking to me with loving words (NOT yelling, swearing or belittling) etc.
Love can be shown with surprises-- coming home from work and finding flowers on the table, getting a babysitter and taking me out to dinner, etc. BUT THESE THINGS DO NOT MAKE UP FOR UNLOVING BEHAVIOR! (But it is so sweet to know my husband thinks about me when I am not there and goes out of his way to do nice things for me).
Loving me also includes affirming me--and often. "Honey, you are so beautiful" at a random time during the day is SO sweet! "Baby, you work so hard by going to work and taking care of this family. Thank you." "Baby, you deserve a break. Let me finish making dinner." These things are wonderful for a woman to hear.
So I don't know how this fits into your marriage, but these are the things that make me a happy wife who is EAGER to please my husband. When I was not getting the need to be LOVED FIRST met, I also wanted to divorce my husband. When he came first in his life, I wanted no part of him. Thankfully God was willing to work with us on this and we have come to a better understanding of each other's needs, and we strive to meet them for each other!
I recommend "The Love Dare" --it is a book from the famous movie "Fireproof" (watch it if you haven't seen it.) "The Love Dare" is a 40 day devotional which challenges you to love your wife in 40 different ways over the course of 40 days. It is tough, it can be incredibly frustrating at times, but if you truly want to save your marriage, it just may work.
I truly hope things work out for you and your wife. I hope at least some of this was helpful to you.
Be blessed.
