Hang in there...
Capt. B.,
I am terribly sorry to hear about your situation. I can't speak from experience, but I can say that I have sympathy for you.
I've been together with my wife for 5 years now and I am grateful that I have the loving relationship that I do. Not being religious, I can't say that God has blessed me with a good marriage. I have to believe that what makes our marriage work is both my wife and myself have mutual respect for each other and we believe in the the vows we took when we got married.
Now then... My advice to you is:
1. Definitely get some counseling from a therapist, religious cleric, support group, etc., it doesn't matter. If you can establish communication between you and your spouse, there is still a chance.
2. Listen and respect what your wife has to say. I'm not saying that you haven't done that already, but it sounds like she has to have her feelings validated from you.
3. Ask her if she still loves you. This is very important. There cannot be a meaningful marriage without love from both sides. She may not like what you have turned into but, nonetheless, she still may love you.
4. Do not trade happiness for change. If you cannot be happy with yourself by "changing your ways", how do you expect to have a happy marriage?
Quote from Capt. Buzzard: "I love her more than life itself, I just haven't been able to show her for a while."
5. If you get an opportunity, SHOW HER, YOU DUMB B^STARD!!!! Actions speak louder than words.
6. No matter what happens, you will be a better man because of it. If you do get back together, make sure both of you have truly learned from your experience and your marriage will stronger than it has ever been.
If you really love your wife, I hope that you can have the courage and conviction to do whatever it takes to see that both of you are happy. I wish you the best and I hope everything will work out in the end.
Keep the blue side up,
