She thought she was losing a bad husband, she really lost a good husband who just got comfortable..
Hi Mike!
Sure you got comfortable. It happens to the best of us. The real question is did you get comfortable in a selfish way or did you get comfortable because life got in the way? Raising kids and working a full time job to support your family should count for something. Sadly, all of the good stuff and the necessary everyday responsibilities are forgotten.
I still argue that the only way we know how someone feels and what they are thinking is if they tell us. When your wife told you that she wasn't happy I'm sure that you did everything you could to try to "fix" yourself and the problem, but she already knew what she wanted but you didn't, so you tried.
Who knows why they do this stuff? Maybe they do get cold feet or they have a sudden fear of the unknown. The bottom line is that until she out and out tells you why she was so emotional and what was behind it, you still don't know anymore than you did when you were married and she was making a case against you!
