I understand the "needing alone time" thing; honestly. I am not married and never have been but I do know if ever it is to happen I will need some space of my own and I will also probably occasionally wanna go off travelling by myself, too...I am just saying I support that bit...because I think many couples tend to think that unless they are CLOSE all the time and do everything together there must be something wrong...
I think after a time this sort of thing can be deadly to a relationship; for me, anyway. Everyone is different and some couples do just fine being in each others' space all the time...
Guess that is why I am alone. I am also not afrid to be lonely. And I think it is fear of loneliness that causes MANY people to stay in relationships in which they are not happy...
