Prayer to mend a broken relationship

Please help me to pray to God to reunite me with the one I love. We were together for 2 years and we’ve broken up over a lot of fighting several months ago.

I know that deep down he is a good man and that I have changed my ways as well, but now he just wants to be free to have fun. Please help pray that God will enter his heart and remind him of why we fell in love so that we may be reunited once more.
