It starts off with lust and at first you are drawn to eachother then its that euphoric feeling that overwhelms every inch of your body and butterflies hit the pit of your stomach when you look into each others eyes.
With time spent together you begin to share common interests and have shared experiences and make valuable memories. Then you get to being in love, that contented and secure feeling of being needed and wanted.
Love is mistaking a pimple for a beauty spot and overlooking a bad habit for being acceptable. After several relationships you find the person that fits you the best. Time with each other strengthens the connection that you feel with your one and only and time and commitment also predicts how you grow with the one you love.
When you see a future with your partner that is when you know you've met the one.
