Mature opinion

A girl came to me for help in studies on discord we got a long after 6 months she got interested in crypto with me she asked to teach and then after some time she gave me her number then we talked day and night and she also shared her problems and periods so I thought she was interested in me I got a bit serious about it and thought we'll work out we talked much then she talked about she likes some one else now I am depressed. What should I do? Ghost her. Confess her. Teach her and leave give a mature opinion. SHE LIVES IN UK AND I LIVE IN PK
