Well, that depends. Does she smile a lot, or is she mad half the time? Is she warm and loving, or is she cold and untouchable? Is she a golddigger, or maybe she doesn't worry about how much money you make? Does she have a job, a career, or will she want to be a "stay-at-home" mom? Kids or not. Does she know how to do stuff, or will you and your mother and sisters have to teach her everything? And if you do have to teach her will she be open to that?
Prettydarkhorse, there are so many, many, MANY, things to consider before even gettng engaged, let alone married, but don't start asking her these same questions, for I can almost guarantee she won't like it, but you can observe, and you can, stealthily, broach certain subjects.
Gals, I wrote this from a man's point of view, but you gals need to look even closer at your man before agreeing to anything.
