Risking your heart

I have been dating one man that I met online.  He is funny, kind and we seem to mesh nicely.  It seems too good to be true.  My last relationship with a man, I was blinded to his faults and settled.  Now I feel if I allow myself to fall for this man, I risk pain and heartache.  Perhaps one must risk their heart in order to find true love......but I don't want to risk my heart.  Too much pain from the past is still so close by.  When does risking your heart have a happy ending?
