Is this love?

I used to be cynical about relationships. I always wonder how people can stay together for 50 years, and still carry the sparks with them. I always wonder how is it that when two people see each other everyday, they still have so many things to talk about. Don't they get bored after awhile? Now I realize, that being in a relationship with a special someone is "addictive".... the more you see the person, the more you want to see the person. The more you talk to the person, the more you realize things about the person you've never realized before, and it's fascinating, and you want to talk more to the person. The more you hold the person close, the closer you want to hold the person in your arms. It's never enough. I guess that's what a whole lifetime with a person is for, to share with each other ourselves, because a day, a week, a month or a year is never enough to be with the person. Is this love? If it is, I'm "addicted"...
