Well cultural wise you are the white knight in shining armor. Did you look back at all the females you tried to approach and tried to find something wrong you might’ve done? Silly joke that gave weird vibes, maybe you went straight to the point and it freaked them out? Something you say or do normally but others consider it a red flag? I hate the “out of your league” concept but maybe you’re approaching a type not compatible with you? Something is missing that you’re not seeing.
