Different types of views from men??? Please?

i am not married, and i havent been in a relationship where this happens but it is the old "bait and switch" things guys are talking about. So you are dating this woman, she is wild in bed, wants to have all the time, go out with friends, joking, playful, takes care of herself...you get married and there goes that woman...not affectionate, different priorities, lets herself go, etc (granted guys can do this too of course! but you wanted a male side)...now I have only heard this, and I know I would be immediately gone from this relationship once it no longer is what I wanted, but you need to keep things interesting, show that you will do whatever it takes to keep him interested (keep yourself appealing as well) and just be fun...
