would you give back your heart to somebody who broke it before?

In my opinion that would totally depend on what that person did to break my heart. Sometimes there are things that seem major at the time (like him finding a new girlfriend) but after the pain subsides you can laugh about it. There are other things that I could forgive someone for (like stealing $1000.00 from me) but that does not mean they will ever have my trust again. To me, trust and forgiveness are two different things. I can forgive a person so I don't have to walk around angry with them, but that does not mean I have to trust them again.

yes and it depends on whether i still love the person deeply or not
