Playing with emotions?

How to know if a girl gives a fake response to everything u do , she says everything in a crying voice acting like she's sad and stuff and happy when the something has happened to u,
Actually I've been in a long distance relationship for an year we hv met once she's 18 n I'm 19...
But she will actually cry and not act so dramatic when she gets hurt or has lost something.. or is happy
How to know if she's just acting along with my feelings
She observes me and doesn't say anything and whenever i ask her about some private questions regarding her past and things related to her emotional or psychological behaviour she always acts like she doesn't know anything,
She acts up all innocent and acts dramatically whenever i ask her something but when she gets caught she tells me everything after i force her to..
Doesn't want to leave me but hides things as welll
But the main thing i wanna ask is how to if she really cares about me and my feelings?
Thank you☺️
