How can you mend a broken heart?

How can you mend a broken heart? If any of you have the answer please chime in.......a dear friend of mine has a daughter who has recently dealt with a potential job loss and now a wedding has been called off.  On top of that he is quite the a**hole and was horrible to her in the end.  So as I was chatting with my friend I started to think....how do you mend a broken heart?  Are there specific steps that one could take?  Is it something that is personal and different for everyone? 
   I wonder because this friend said to me that my advice was better than anyones.  I did not offer what I considered to be advice at all.  I shared my personal experience in recently dealing with a broken heart and an a**hole but did not think I was telling her what her daughter should do.  I don't know what her daughter should do.  I do know with anyone whose heart is broken you should set some firm boundaries and hold them.  No matter how enticing weakening them might seem.  The brief reprise from the pain will only serve to make the pain that much worse when it returns.  And, it will return.  So, what do you do?  A very wise Dr. that I once worked for said that sleep is important.  If you can sleep, you can get through anything, he said and at the time it made sense.  Sleep it off like a drunken Saturday night. :)  Some say forget about him....is that good advice?  Shouldn't you want to remember so you don't repeat those same mistakes?  I can honestly say that over the years I have adopted the forget about it attitude only to find myself right back in the same position with a different person.
   Broken hearts suck but they are not permanent.  I have recently begun to really believe this and I hope with all that is in me that it turns out to be true because they do suck.  But however temporary they may be they are so incredibly painful that the desire to get relief from the pain even for a moment can be so great that we jump right back into a situation that will only end in another heartbreak.  I am committed to not doing that again.  But I would love to hear any thoughts that you would care to share on this topic.  I should also go ahead and put in a quick plug for my fabulous therapist who has taught me so much in such a short period of time  Ms. Alexandra "Ola" Stasiak-Brough.  I must ask her where "Ola" came from.  Sorry, that was me chasing shiny objects.  Anyway, she is good so if you need a good therapist call her 404-771-1649.  Be sure to mention me in case she ever decides to give away prizes for referrals.  :)  And do share your thoughts.  Blogs are not fun if no one responds.
