Did I already post? These kinds of topics seem to run together.
I'll just treat it like I haven't.
First, age does play a role simply by that [hopefully] as you grow older you mature as well. You then have to figure out if this "love" is just a crush or if it's really love. Love is something you have to work at and a crush is just immature love. A crush basically creates another person in your mind taking only the good things and making the person seem perfect. Real love accepts the whole- not just the person in the figment of your imagination. That is a crush, that is immature love.
And no, love is not "when you get butterflies in your stomach when you see them" as the cliche on those avvies go- it's so much more than that.
"Love is patient, love is kind. It does not envy, it does not boast, it is not proud. It is not rude, it is not self-seeking, it is not easily angered, it keeps no record of wrongs. Love does not delight in evil but rejoices with the truth. It always protects, always trusts, always hopes, always preserves."
-- 1 Corinthians 13:4-7
