A question about love and hope and happiness?

i married my husband not because i was blind with happiness and love,and attraction, like some people experience. I wasn't. i was preatty clear headed, but i couldn't imagine my life without him. now i look at people, and i see some that are so in love, and, without wanting, doubts and fears come upon me. and sometimes i wonder, 'did i miss my true love?' since, i didn't feel those feelings of hopelessness, huge erflies, ecstasy etc., did i settle for second best? yes, maybe some will think so. but the truth is, i would never leave my husband. he is a wonderful man, who would give his life for me any second. i love him very much also. is it possible for love to grow after you married? is it possible for our relationship to grow to that perfect love, even if i didn't feel those feelings at the beginning? could he be the one anyhow? does someone have a similar story? thanx :)
