How do you know if you love someone?

I mostly feel weird when I see the girl; I imagine myself kissing with her. I feel the urge to touch her and talk with her I pay attention to her clothes when i see her a few times a week. I also take notice of her body language to see what her social borders are. Perhaps you could explain your situation and we'll help you out.

there are many factors to consider to know if you are really in love. one way is to stay away from that person, if you cannot, initially it means yes. sometimes you will feel how he/she does its because you are in love. but these are not limited basis a lot of things to consider. well it depends on one's perception too.
