Do not engage with someone with lower behavior.
You will be dealing with someone who projects,
who has ego problems,
who is self centered,
who lacks empathy,
who is emotionally immature,
who has unhealed wounds of their own,
who has a need to feel superior,
who needs to control others,
and who ends up hurting just about everyone who crosses their path.
Stay away from such people & such behaviour.
Move forward by healing your own hurts.
And forget about inviting other’s toxicity into your space.
You are your own responsibility.
Make sure you make yourself a better version of yourself with time.
