Can it really heal? Doesn't it leave a scar?

A lot of thoughts in my mind...
Both pain and guiltiness filled me.
Mixed feeling.

I questioned myself "Do I know what is love?"
Indeed, I'm still quite unsure.

A friend shared these with me:
We spent too much time looking for the right person to love or finding fault with those we already love... when instead we should be perfecting the love we were given...

In life there are very rare chances that you'll meet the person you love and loves you in return. So once you have it.. dont ever let it go, the chance might never come your way again...

When you truly care for someone, you dont look for faults, you dont look for answers, you dont look for mistakes. Instead you fight the mistakes, accept the faults, and overlook the excuses...

one can never have the best of every thing in the world, they just make the best out of what they have.
the worst thing u can have is regret.

It isn't easy to perfect the love. I'm tired......
I'm the one who is always finding faults, looking faults and mistakes, so does it mean that I don't truly care?
Contradiction. How to ever perfect the love, when you don't find faults and mistakes and instead fight the mistakes, accept the faults and overlook the excuses?
This is not perfecting, but this is compromising, isn't it?

P.S. 怎麽了 我累了 说好的 幸福呢
