You could be rejected and not understand what’s happening. So let me help you out. When you keep reaching out, and they don’t reciprocate (return the gesture) it may be that they don’t want to talk, be friends, or communicate with you any longer. You should understand that most relationships are meant to be lifelong.
Try not to be upset if you are being ignored, avoided, or even “unfriended on social media”. See your own worth and decide that you are going to be adult about this, and even be okay with greeting them with a smile if you see them in passing.
So have your moment of “How dare they reject me” then tell yourself, If they want to go, let them go!
1 Peter 2:4 ESV, ” As you come to Him (Jesus),He is a living stone rejected by men but in the sight of God chosen and precious”
