I used to say the same things to my buddies after they got married.
I'm a pure a$$. I warn all girlfriends. "I'm a guy. I do what I want. If you can deal with it, we will get along. If not, you need to move along..."
Selfish? Yep. Shallow? Yep.
Not so easy to do after marriage....you really have to pick your battles. A gf might agree to deal with it now, but after the wedding cake is cut things may change. I was sort of like you at one time, but you learn to compromise after you tie the knot.
I'm actually quite lucky....I was being fecicious about divorce and such....my wife would probably be okay with a manual, but I wouldn't be okay with buying a car that we could not share.
