Oh definately! I have loved and lost a few times, this just helped me know what I was looking for, then I found him, now I know how to love and keep him. The only way to learn is to experience things, as painful as it is to lose, its all made easier with time and makes us much more cautious in future, that can only be a good thing!
Many people never fall in love.
I did not realise this until I was in my 30's when I did!
It IS better to have love and lost than not to have loved at all but try to keep him!!!!!
