Prayer To accept the end of a relationship

My fiance chose to end our relationship because of my Christian faith. He attends church but has never fully believed in God or committed his life to Christ. Less than a month after he broke it off with me, he reconciled with an ex-girlfriend who’s an atheist.

I love him and my prayer request is that God will be in control of his relationship with her and in my ability to accept his decision and move on.
