trrose- You missed a lot there...you got a lot more out of her than most do. Going out is clearly important to her, reasonable or not. Is that a concession you are willing to make for your marriage? Going out a little more? Because what you did was a) pointed out that you both are starkly different in that area and b) implied that you are morally superior because you recognize that it is better to stay home. Now, in my sitch, this was a HUGE issue but in retrospect, I wonder why I fought H so much on going out more...
It is good to be honest AND mindful of how you present things.
Listening to friends is great but you must remember that each sitch is different and certainly each woman is different. You are early on in your sitch and you may really be able to turn this around if you pay more attention.
Your wife wants to go out and have fun and you don't, so she does it without you. I was there (in your shoes)...I can't say it would have saved the marriage but I don't feel great about having refused to go out more toward the end...
