Okay.. I did a google on "Signs you're in love" and so far, I checked these:

1. You’re in love if you think about them all of the time.

Well yah, I didn’t say that everything on this list would be profound or anything. This one is a no-brainer. If you love someone, they’re going to be in your thoughts all the time. In fact, you won’t be able to get them out of your head. Look at the rest of the indicators before coming to a conclusion, though, because this one could also mean that you’re just plain nuts.

2. You’re in love if everything reminds you of them.

Someone asks you to pass the ketchup and it reminds you of them. A flock of geese fly overhead and it reminds you of them. You get the picture. Oh, and for some reason, when you’re in love it seems like every new person you meet or see on TV or hear a story about has the same name as the person you’re in love with. I don’t know why that is, it just happens.

3. You’re in love if you start caring more about your own appearance.

Suddenly, without warning, you find yourself wanting to actually iron the wrinkled jeans that have been sitting in the dryer for the last three days before you wear them. If you’re about to see that person who you can’t get out of your mind, there suddenly seems to be a whole lot of reflective surfaces around to check yourself out in.

4. You’re in love if you’re actually interested in knowing more about them.

You can forget about the days when you went home from a date remembering absolutely nothing about the interests, career and dreams of the person you went out with. Finding out all about this fantastic person is your new favorite thing to do. If you could find a book detailing every minute detail of their life, you wouldn’t sleep or eat until you read every last paragraph.

5. You’re in love if you want to impress them.

You’ve always tried to be modest, but suddenly you feel like you’re a politician fighting to win the most important election ever in the history of the universe. You make sure that the faded newspaper article about you winning your third-grade spelling bee is left nonchalantly on the coffeetable when they come to visit. And you keep them as far as possible from that great aunt who loves to tell all of the embarrassing stories about you.

6. You’re in love if you aren’t as tight with your money or time anymore.

There was a time when the idea of shelling out your hard-earned money to buy someone dinner or a gift would have horrified you. Sure, you would buy an occasional round for your friends or bring grandma flowers on her birthday, but spending any more money than absolutely necessary just wasn’t going to happen. But now, no price seems too high as long as it makes that special someone happy.

7. You’re in love if hanging out with your friends just isn’t as appealing any more.

Remember when you and your friends made fun of the former buddy who ditched your gang to hang out with their new boyfriend or girlfriend? And when the thought of abandoning your friends to spend time with a member of the opposite sex seemed like sacrelige? Well you can try to deny it all you want, but you’re finding yourself constantly thinking about being with that special someone . . . even when you’re surrounded by your buddies!

8. You’re in love if commitment is actually starting to sound like something you could stand.

What, you commit to something that requires you to be faithful and responsible? Oh, the horror! What strange, evil spell has been cast upon you that would actually make you excited about a long-term relationship or even marriage with someone? Did someone slip something into your drink? Are you going insane? No. You’re probably in love, knucklehead.

9. You’re in love if you just aren’t noticing other members of the opposite sex.

Oh, the people you used to stare at are still there . . . you just aren’t noticing them anymore. For some bizarre reason, that special someone has suddenly become infinitely more attractive to you than any other person on the face of the planet. People who you used to think were good-looking suddenly pale in comparison to the one you’ve found yourself falling in love with.
