You can tell which guys are married and not in this thread and any guy who says that another should grow a pair is obviously in the later category
I think in any successful marriage, there has to be give and take. Now this does not necessarily have to be a 50/50 split as some personalities are more giving than others, but as long as a couple reaches a balance that both are happy with it is ok. In my marriage, I probably compromise more than my wife, but I am fine with that (happy wife, happy life) and it is not like she doesn't do things that are entirely for me.
As for spending time with the buddies, I don't have any in the city so this isn't an issue. I am more of the introverted, homebody loner type anyways so it doesn't bother me. Frankly, I would rather spend my time with my wife and can do most of the stuff I would with a guy anyways (she's a sporty kinda girl) which is why I married her. If my wife wants to go out with her friends, I have absolutely no problem if she wants to.
When it comes to spending money, my wife and I have the $100 rule. That is, if an item is more than $100, we have to get the other's permission, excluding gifts. Honestly, I cannot recall a time when the other has actually said no, it is just a good way to communicate with each other.
