It's better to have loved and lost than to have never loved at all.what is your opinon on this?

yes love is great..but when you get your heartbroken it is the worst feeling in the world..maybe sometimes its better to not love..so you wont get hurt..bc i feel like so many relationships now and days just end up in heartache.maybe we should all just fool around with eachother and not get so attached..because this feeling sucks..how do you guys feel about it?
