Why do people, mostly couples trap in a lie? When the real reason is just not telling. Don't know why, many assumes that not telling is not a lie. Some story are meant to remain a secret or just history. Because not everyone can accept someone's past. It's for everyone sake to ensure a long life of happiness.
Some past are too dark that it's just for personal keepsake and never meant to share. Some past is too sweet that it'll hurt someone's heart. That's why not telling is not a lie.
Don't get me wrong, I did not aim at any specific gender. This happens to all, whether the boyfriend or the girlfriend. If married, it's either both the husband or the wife. Each of you are just protecting each other. So don't ever misunderstanding that not telling is not a lie.
