a child faked her age to go out with me

I have been talking to girl for about 2 weeks and for context im 19 this year im goona be 20 and the girl told me her age is 19 now we went to the first date yesterday and we went to restaurant and she was nice and all and we even started holding hands and all but we went to watch the movie macro but it was "A" rated and it was booked in pvr and the guards had to see our id , i showed them i got clearance but when she took out her phone and showed the guards her Adhar they told her she cant enter cuz she is below 18 i mean she was 15 for fuck sake i mean my niece is elder than her . i was like wtf dude and for obvious reasons i dunno why she started crying then i booked a cab for her and ghosted and blocked her , i mean what the fuck was that

update - the girl tried to contact me several times and just 1 hour ago i thought of talking to her and first of all idk man why girls start crying without any reason , goddamm i hate it i explained her that whatever she did is not right like lying about your age then roaming around with a guy who is 19yr old , i told her if there was any other guy could have taken advantage of you and told her she have block me and leave me alone cuz this is not right to which she agreed
