With time, one develops the EQ to see if they are gonna reciprocate or not. Hence, now I stop at the point which won't hurt me back.
But before I stop I communicate with the other person and if the other person says "I am busy or not available emotionally or bla bla". Then I move ahead. Otherwise I put down more effort.
Since, your question signs that you MAY Have got hit at your self esteem - then answer is:
A man has to keep on working at himself, taking complete responsibility for whatever happened even if he wasn't part of it. If the war is happening in Ukraine and that is impacting my promotion, still I need to take 1000% responsibility of it. (HENCE I SWITCHED LAST QUARTER, AFTER HEARING THIS FROM MY 6 LEVEL UP MANAGER IN 1:1).
Hence, men have to go up and beyond to take responsibility to uphold their self esteem also, while being ready to put efforts the next time a "potential right person" strikes.
