Question

Why we get very close to some people & when we leave them, we feel bad?

Answer 1

That's because we've spend such a good time with them.  We came to like or love them as a close companions in life.  We're bonded to those people that we learned to love somehow.

Answer 2

I think because you have spent quality time with them. You've  had experiences together and when you part.... the period is over. It's sad when things come to an end. All that fun and experience you've had with that person (whether its one day or 1 week) turn into memories. Its sad to say goodbye.

Answer 3

When you are in a special fix, you think its forever but it never does.

A lot of fixes makes you hard but you appreciate a woman the most when you lost her.

We both feel bad because true love becomes ugly pain that can't be measured. And you move on...
