Is love even worth the risk of potential heartache (everyone's opinions)?

I mean yeah love is great, but there are some things that can totally leave someone down in the slumps (i.e. being cheated on after being together for 5-10+ years)...and other things. This probably seems like a dumb question, but try to pretend you have already experienced the heartache downside of love...would you want to take the risk knowing maybe next time you could be hurt more than you were the first, second, etc, time?
