I believe that there are only 2 types of love. So here are my thoughts on both:
Compassion: Is the type of love that makes you want to be around that significant person. When you are away from that person all you can do is think about that person. I believe compassionate love comes from a person's heart. This type of love needs to be founded on companionship, dependability, and trust. With these key concepts a relationship can last forever. I believe if a relationship is founded just on lust then that relationship is doomed to fail eventually.
Sexual: Is the type of love that is pure appearance and arousal. There are many people who are physically appealing so there is no point in rushing to have a specific person par take in sexual love because there are a lot of fish in the sea. I'm sure this type of love is nice to par take in but it is not that important unless you believe love is a numbers game to see how large your body count can get. If a person is so worried about sex then they can stimulate themselves they don't need another partner to feel this type of love.
Based on all the information I have gathered from my own love life as well as others I believe compassionate love is what will keep a person coming back to that significant other in there life.
