You think it's cool to connect and flirt with multiple girls. No, it's not. You have taken advantage of someone's feelings and emotions who loved you. You have ruined someone's life with lies.
You have no right to hurt anyone. You have no right to play with someone's feelings.
Don't enter into someone's life if you don't want to pursue them. Never use anyone for your own benefit. Never hurt anyone because for you it might be just a time pass or fun but for some people it takes decades to heal from that pain. Never be the reason of someone's pain. Because when Karma plays back, it won't spare you.
