No more heartbreaks

How do we try to avoid heartbreaks? Are we even able to completely avoid our hearts from breaking? Who to trust? Who do we trust? How much of our hearts can we give ? How long do we hold onto a heart break? We have to be mentally conscious and aware of how and when our hearts almost getting into that heartbreak zone so we can protect it! We are humans and not perfect, so we will fall and make mistakes, but it is our responsibility to learn carefully from it and do much better so we can deserve much happiness. Of course, the Lord helps if we allow Him.
