Wicca/Pagan Spell to fix a broken family?

My mom and dad do not love each other anymore. They constantly fight and they always talk bad about each other to other people. My mom works endlessly around the house and my dad is very lazy. They always fight and my dad even wants a divorce. I want a spell to mend a broken family and relationship. I am preparing for this now since there is a waxing full moon approaching very very soon. Anybody have a good spell they can share with me to help me? It would help me so much :)
