Questions on love...

I am staying at a friend of mine in Varna.
She recently had to part with her boyfriend, whom she met while working on an ocean liner. And the boy really loves her. She made her a DVD, with the people at the ship, with his confessions.
I wish someone did this for me...
And I have some LOVE related questions:
Why is everyone so fuckin scared to love?
Why is love a synonim to having?
Do I need to concentrate my love in one person to be happy?
How do I learn to be happy without "having" someone?
I met my ex-boyfriend and it felt so cold.I am walking down the same street where I lived through so many challenges in the past years in Varna. Why do I feel melancholic about AIESEC then? I do not feel melancholic about my relationship...Have I taken it for granted?
Then...why do I feel so much for places, songs, food and drinks I shared with a person I never had a physical relationship?
Will something be changed after his lie?
What will I feel when I see him with the person he likes?Will I cry again?
And, why the hell I feel so free of my emotional burden here in Varna?
I will put them on my back again when I come home to Sofia, for sure...
If only I could...leave throw them into the sea.
