Symptoms of love or lust?

[codependency]

I am 22 years old, although i have had 4 girlfriends in my life so far.... i still do not understand myself sometimes.
well to cut the long story short, i haven't had any successful relationship so far,
no matter how serious i was with the girl (i was cheated twice by my 3rd and 4th)
anyway that's a different story.

Recently i have been seeing a girl, i have only met her twice, though for that each day we spent almost a full day being together
watching movies, going to the beach, lunch, dinner, garden , and i have invited her to watch movie with me in my house.
But there's nothing else happened between us.
I met her on a forum under "looking for friends" category.
So i have been assuming that she is just seeing me as a friend.

Me, however, I think i have grown to like her after my 2nd meeting with her...
I know this is maybe too fast.
but if i am to be honest, i would be lying to say that i only see her as a friend

How to know if you really love someone? Am i just feeling lust and perhaps i am just feeling lonely because of my previous experience with girls?
So far here are the symptoms i have been showing:
1. She is the first thing i think of in the morning ; and she's the last thing i think of before i sleep
2. Just by talking to her, i can feel happy
3. I checked her star sign and mine to find our compatibility
4. Recently all i have been doing is googling about love
5. i check her facebook's page every day
6. i look at my cell phone to see if she either called or messaged me
7. i looked through my email to see her previously sent messages
8. I have been researching about places and activities that i can enjoy with her
9. I fear being rejected by her
10. I think of her at least few times in a day
11. I look at my watch and wondering what she's doing at that moment
12. I want to meet her at least twice a week
13. I feel like i do not need anyone else when she is with me
14. though i am usually silent, i am more talkative when i am with her
15. I am resisting myself to contact her too often as for fear of losing her
16. I listen to her and i am willing to do anything within my ability
17. I get depressed when she does not respond to my message
18. My mind keeps calling her name when i am day dreaming
19. I want her to rely on me and be useful to her
20. I feel so lost without her

how do you know when you really love someone?

by this symptom 13. I feel like i do not need anyone else when she is with me
you are totally in love. Good luck at getting this lady for you

You have this whole Romantic Fantasy Package that you have tacked onto this girl like a big fluffy dress. Remember, you hardly know this person. This whole list of stuff is about YOU, not HER.

So no, it's not love. It's not even lust. It's neediness.

You met her twice. How can you be possibly in love with her?

very valid point.
i guess both of you are right

i need to rethink about this slowly
