what do you do in these situations?

Lets say you have a crush on this person and that person says I like you and you say I like you too. But you just realize how can this person like you if they met you like 2 days ago. but you just say I like you too because that person is cute. but then you start to realize that that person hardly text you. Like who hardly text you if they like you as a crush. right no one. then you start to ask questions like do u really like me and stuff. And they say yes. But do they really mean that. or is it just an act. And that person does not like you as much as you thought. in my opinion- That person does not like u! they think they do but they don’t. Im not trying to be mean but this happened to me and it hurts trust me so take my advice and go on that person does not like you and you don’t want to get hurt just like me.
