I think different girls want different things similarly to how different guys want different things.

Part of the problem with the wanting to spend all your time together... Is that that tends to result in unhappiness in the longer term.

For example... There can be someone in your life who you love very much. Your best friend. Your mother. Your sister. You can love and appreciate them a great deal but you don't have EVERYTHING in common with them. So you go off and do your own thing, go off and hang out with different people. Sometimes that can make the quality of time that you do spend together a lot better. You have other stuff to talk to each other about etc.

Of course things tend not to work if there isn't anything in common and the couple doesn't really want to spend any time together. But I do think that there is this negotiation of dependence and interdependence... Of time together and time apart... That makes human intimate relationships the hardest thing in the world.

I personally would be wary of a guy being too 'clingy' - of feeling guilty if I wanted to have a night to myself to wash my hair etc... If I wanted to go out with other friends... But I'd similarly be wary of a guy who was too independent. Who didn't seem to want to spend time with me compared to his other friends... Who didn't seem to enjoy spending time with me.

I think it is a compatability thing.

But... The thought that you 'aren't complete or whole' until some other person comes along and completes you... Well, in the words of alanis morrissette (who has boundary issues to be sure) 'I believe that one and one make two'.
