Ego makes you rude and love makes you humble.
- Leave him for some time. Let him fly in his own sky. Let him realize your importance (If any). He will surely come if he loves. Else he fly away even if you try more.
- You are loving friend and not begging. Its okay , that one partner should be more caring if other is more immature or childish or weird. But there is a limit to every thing. Some times the other person turns narcissist and start to enjoy your attention and pain. Leave him at least for some time. He has to rebound at some point of time.Else he is just not worth it.
- Som epeople specially the egoist one’s rebound very hard , if you leave them for a while.
Pro Tip : Use your discretion and use moderation, if you really love. Everything should be under the flag of love.
