Who should one marries?

Why do some people find it difficult to cross over from courtship to marriage,
while others can't wait to cross over from courtship to marriage because of their age.
I think I belong to the group of minority of woman in their 30s who are not eager to move over from courtship to marriage, for whatever reasons, I'm still thinking about it.

Somebody told me that you should marry someone you can't live without, but you should not marry someone you can live with.
Without thinking, I know that he is someone I can live with, but the irony is also he is someone I can live without.
But as I ask my own heart, I begin to realise why I have made this choice in choosing a man.
I don't want to live in heartache, agony & pain one day if he's not around anymore, or our relationship doesn't work out because of some reasons.
I've heard of too many stories & experienced too much heartaches in the past that I would never have the courage to follow my own heart & chase what I want now.
I think I'm really quite a selfish person with regards to love actually.
I don't know whether he knows how my heart is feeling right now?
To him, am I also someone he can live with, but also someone he can live without.
But I guess for a guy, its a totally different issue afterall.

As I read back the entries written in my blog few months ago,
I realised that many months ago, I have actually lifted up all these issues onto god's altar and I actually prayed for something.
But now I'm so afraid that my prayers are slowly being answered, or are they not?
I wonder......Should I marry him? I'm already 32......I'm going through what E is going through few months ago......Oh god, please help me......
