These superficial types of men are doing you a favour by revealing early on how much of a waste of time they are. I went through that and it was awful, being rejected for tiny flaws (one guy said ‘if I can put your personality in my gorgeous but stupid friends body, you’d be the perfect woman’).
Work harder on loving YOU. You’ve got to get your own vibe right. You’re devaluing yourself based on those last few kilos- the men folk pick up on that kind of stuff. Until you completely love, respect and cherish your own body, you’ll be fighting this battle over and over and over. When you start seeing yourself as worthy, beautiful and desirable, that’s attractive. Confidence is sexy.
You are already a very beautiful woman (I can tell from your picture) I think you just need to start seeing yourself that way too. Ditch Insta. It’s like sugar (poison) for the soul.
