When people are young they mistake love for lust or infatuation. Love lasts period. It's not a feeling, it's a decision. It's a commitment to a person for the rest of your life. Most young people have a hard time grasping that concept, or simply are never taught what real love is.
I was blessed with a young love and it has lasted 37 years. Although it seemed infallible back then, it was tested over the years .. many many times .. but we reinforced it along the way with compromise, tolerancy and commitment and have been fortunate enough to see in grow into something I didn't even know that existed. It is stronger now than it was then.
Well, I would say young love lasts about 8 inches long. Once the sweat has dried, what was your name again? Don't give yourself up easy, ( not that you do), but this is practice time. You learn who is serious and who is a screwball and who has the personality traits you respect and agree with. Hopefully you pick someone that has drive and ambition, and will take care of you and the offspring. In the meantime, educate and prepare yourself because you never know when you may have to rely on just yourself. Don't worry so much about love, it'll happen, just don't allow yourself to accept less of a man than you are a woman. That's where the conflicts start.
