loving it, hating it

i don't know how the life can exactly be if i ever get into a relationship again.

what i'm feeling now - the urge of missing somebody and wish not to be missing somebody makes me, very uneasy. Though he sounded all right, though we both, sounded, comfortable with each other.

is it a pre-emotional stage of falling into - something called love, again?

I know it clear loving somebody again is never easy, for me.

Can I just be with someone comfortable, for a long time, enjoy the companionship, without thinking of - Love?

A companionship driven relationship VS a Love driven relationship.
How much of these can the emotions handle? and constructively build the future together?

And either way the relationship will get complicated.

I am just wondering whether I am ready enough for the forthcomings.
