Is passionate love worth it?

7 years ago I fell deeply in love with a man who didn't return my feelings. When he rejected me I was crushed, and for months I cried every day over him. I have moved on with my life, had other relationships since then but every now and then I think of him, wonder if he's happy etc. Bad enough? Well I recently fell like a ton of bricks for a man who has ignored my phone calls and emails. I've accepted that he doesn't want me and no longer try to contact him but I cry every day when I think of him. I think about how incredible our chemistry was and can't believe that he could just walk away from that. I'm dating and hoping to find someone I like better but I never loved any of my boyfriends as much as I loved these two men. Considering how passionate love has given me nothing in return should I just stop looking for it and just settle down with a good friend? What is love worth if it doesn't help you connect with people.
