Disrespecting a man just to push him away so you can be with someone else is a form of mental manipulation and emotionally irresponsible behavior. If you want to leave, leave with honesty. if you've moved on, say it with integrity. Creating pain or confusion just to avoid
a truthful conversation is not maturity it's avoidance. Respect shouldn't disappear just because feelings change.
Communication is maturity.Honesty is courage.Respect is non-negotiable.
