Women are so confusing?

So i was in love with this girl.. our families are very close to each other she is my mothers friend daughter... She occasionally comes to our house with her mother on vacations especially... For many years i never told her that i liked her until recently i told her.. she replied i like you too after couple of days... she was very friendly in the beginning and we were in a relationship... we cuddled each other especially when we were watching movie together... one day we were cuddling on bed and i was really turned on and she was too.. we had sex and i could tell by looking at her that she was alright with it and enjoyed the time everything was alright... Next day she told me that she was not actually into me and didn't love me... she told me that she didnot know why she said yes to me when i asked her did she love me... i calmy replied ok with no drama but i feel so disturbed right now bcz i love her... Does anyone know why she did this bcz i cannot understand it.
