Your wife should alot like my ex-wife. I put up with her crap for 18 years, while she stayed home and never could make her happy. Then after 18 years, I finally lost that attitude that I will do whatever it takes to make her happy. I became aware the life is way to short to live on a day to day basis with such disfunction. Onice I didn't care anymore, her threats to leave me had no more meaning, she lost her power to manipulate me by using my love for her as a tool.
Now, close your eyes and picture yourself with a spouse who not only loves you, but respects you! Picture yourself with a spouse who you consider your best friend, one you can't wait to spend time with on the weekends because you like doing the same things. a mate to travel with and experience new adventures together instead of door knocking every weekend. One who you know will always have your back and will not betray your trust.
It took me two years after I divorced to find that person, now I wonder why I put up with that crap for so long. I am happier then I have ever been in my life and she is still as misserable as ever. The break up was very painful and a major set back financially , but in the long run, I am so much better off and only wish I now had done it sooner.
Don't waist a day with someone who you will never make happy. Or you can let her slowly kill off your love for her one day at a time until you finally wake up one day and just don't give a damn anymore. Life is short, go live it to it's fullest.
