Passionate love vs Secure love?

I'm in a semi-new relationship with a good guy. He's sweet and faithful, and I could see myself loving him one day. A guy that I have been dating on and off for the last couple of years expressed interest in a relationship with me around the same time that I met my current bf. I turned him down because I didn't want to get hurt again, but I still love him. I know that I'll never love my bf in the same, passionate way that I love the other guy. Did I make the wrong decision? I know my bf will never hurt me... But did I give up the love of my life for emotional security?
