How can you be sure its love man? I believe love is something that grows and you have to know someone (inside out, or at least pretty well) before you can say that you have those kind of feelings for a person.

What your feeling is most likely infatuation, lust.. you are attracted to her because of her looks and good personality, but would you do anything for her? would you kill for her? would you die for her? would you do absolutely anything in the world to make her happy? Ask yourself those questions because I dont know the answer but i doubt it.

Well when i was young around your age i've been in this position before where i seriously thought i was in love after having a little holiday romance, because at that time in your life its a good memory and really special to you, but trust me you will get over it in a few months and when you get older you will look back on this and realise it was just puppy love.

When you get older you'll realise that in love, the "feeling of shit" you have now is NOTHING, it can be a million times worse, but on the flip side the good feelings will be better aswell.

Just dont worry about it mate you will get over her ok.
