I also thnk it can depend on the person you are in love with. I was in love with my college boyfriend and I'd describe it as the always smiling when you think of him, caring for his well-being, making me happy kind of love. But he was really laid back and a totally different personality than my husband.
As I've gotten older and lived with and am now married to my husband, a lot more issues come up that are more serious than college and it's not the same for me. Sometimes he drives me nuts and definitely doesn't make me smile!
But I always feel I would be happier arguing with him then never being with him at all. I always tell him he knows I must love him because I wouldn't put up with him if I didn't!
Plus, here's a good one my girlfriends and I laugh about - you know you're in love when you can pass gas in front of them!!!
