People tend to make mistakes because we're humans.
The term that says "love is like a glass, once it's broken it can't be fixed" but is that true?
Some broken glass is easy to repair on your own, assuming you have the time, patience and skill to do so. Other glass pieces are too delicate, valuable or complicated.
This depends on how hard you try to fix the glass and how delicate the glass is, but if the glass is broken several times buying a new one is a lot easier.
Forgiving is good thing but don't forget to love yourself.
