It is most likely a serial cheater would keep on doing it...therefore if I would ever meet another one in my life, I would dump him immediately. I have learnt that self-respect is even more important than love.
Who does not respect you automatically does not love you.
A friend offered me a lunch, but I refused by saying that I already had it. Then, at his insistence, I sat down and ate with him. And he showed distrust to me saying:"If you tell lie in such trivial things, then how can you tell the truth if it threatens your own life?" Because of this valuable lesson, I made my mind to check more carefully my words to be always truthful.
Yes, I have.
At least once a week.
