Most men don't marry women for exactly the way they are any more than most women marry men to change them. Mostly this is because few of us ever really know either a potential partner or even ourselves, and just to complicate matters people do change and grow over time. A habit that may have appeared endearing in the "honeymoon" stage may later be intensely irritating. The rest of the universe doesn't stop changing either, and people change as a reaction to that. The other thing that can be a problem is not really seeing the person behind the expectations, both of what you think/hope they are and what (often without realising it) you expect from a relationship. Love can conquer mountains - but it often falls at a molehill. If you communicate, share ideas and expectations, work at it, and are lucky, you may find, recognise and keep someone to love and share your life. Meanwhile work out who you are and what you want.
