Well it can have a lot of reasons
Every body can say this :I LOVE YOU"!!!
First :probably that persons do not really love you
Second :need some space to think about you
Third:that person is a cold person and does not speak a lot (her personality is like that )
Fourth :he/she is really busy
Fifth : She/her is a little shy and waits for you to start talking
and so on...
.
**in my opinion I think people "pay for their words "!! I mean don't speak a lot .!!!
En mi opinión, creo que dependería de tu relación con esta persona, ¿qué tan cercano es él / ella a ti? :) Tal vez solo necesite tiempo para pensarlo. También depende del tiempo que hayan estado ausentes. No espere demasiado, pero no se rinda demasiado pronto. Tienes que averiguar qué parece correcto. ¡Buena suerte Rei Rei!
