I don't usually get involved with things such as this, but I gotta just say this...
I have a real problem with someone who pulls childish sh*t like giving the silent treatment, giving the ol' stink eye and, basically, not just coming foward like an adult and voicing whatever the hell is stuck in their craw. I also have a problem with the idea that a man has to somehow plead his case to his better half, as if she is judge, jury and executioner....as if they must be sold on a given idea and then give a man "permission" to do whatever it is they want to do. In many cases that may be the reality, but a man's goal in life is to find a woman who doesn't act this way....and who is gorgeous.
I've blown through one marriage. Let it be known however that the first one was reduced to ashes simply because I made the mistake of marrying an 18 year old girl who turned out to be a complete and total whore. Go figure. Marriage number two has been pefect since day/date number one, and for quite a number of years now. Why? Because we each respect one another. And, I keep her very comfortable, very satisfied and very happy. So when it comes to my endeavors such as cigars, libations, boats, cars, fishing gear, etc., she gives me no problem. If there were a legitimate concern on her part about something I was doing, she's adult enough to come to me and say, "You know papi, I really am concerned and feel that...." When she does that, I listen to her and respect her opinion and generally, for the most part, adapt accordingly because I know she wouldn't have come to me in the first place if it weren't really something near and dear to her. Compromise on some things, respect always.
The bottom line of all this? I don't know fella...you gotta NOT cave in immediately simply because your gal gets something up her rear end and then decides to sulk about it. Maybe she's concerned about you, maybe she's just trying to change you. That is a goal of many women after all. So which is it? Well, go to her and tell her that you'd appreciate being treated like an adult and that you'd like her to act like one too. The secret to a happy life is finding a gal who can do this. And then, keep her happy. By the grace of God, I did on round number two. But from the sounds of it...getting "pissed," acting childish as she has, to me that doesn't smack so much of geniune concern than it does she's just trying to get you to do what she wants you to do...for her sake, not yours. Now, if this were a scenario where's she's been begging you to stop for years and years, and you've blown through one promise after another, that's a little different. But as it sounds now...I'd stick to my guns.
