Love is not jealous... ??

Love is patient, love is kind and is not jealous; love does not brag and is not arrogant, does not act unbecomingly; it does not seek its own, is not provoked, does not take into account a wrong suffered, does not rejoice in unrighteousness, but rejoices with the truth; bears all things, believes all things, hopes all things, endures all things.....

Love is not jealous? i don't understand. how can love not be jealous? love is one of the most strongest feeling known to man and women. though i guess when i think about it, jealousy would be considered unbecoming. but i still don't understand. when it comes to love, or more directly, when it comes to my fiancee, who i love more than life itself, then i'm more jealous than i probably should be. it is somewhat consuming, and not something that i can control very easily. in fact, it's almost impossible. i don't know how to control it, but since i love him as much as i do...wouldn't it be simple and easy to control and not let things like jealousy rise up?
cause honestly, i'm very very jealous. i'm jealous of his love, his time, his attention, his work that gets him more than i do. i'm jealous of his every glance, anything that passes in front of his eyes, everything that he touches, everyone he speaks to, anyone who sees him...especially if that someone is a pretty girl, a girl prettier than me...i wish worts on her face so that he might not find her attractive in anyway. (which is very wrong of me, i know...but kind of fun ^_^ )
so you see, that is why i don't understand how love is not jealous. but i am so deeply in love, and so very jealous of everything about him...? i don't get it. :/
