@chbartist, Yes, in life we face these kind of situations where we waste our energy unnecessarily and it was not required. And for sure our Innerself is great teacher and guidance and it will going to guide us time to time about our Beneficial aspects through vibrations so, when we get to know that we are wasting our time on someone or something then we should stop it and we should focus towards other aspects where we receive Positive Vibes.

Wishing you an great day and stay blessed. 🙂
