When Your Parents Divorce:

“ in any case forgiveness can be a challenge, I pray and ask God for strength. I ask Him to change my heart to be graceful toward others, just as He is graceful toward me. Daily as I choose to forgive and not become bitter, negative feelings flow away and peace floods my heart.”

This is an excellent article to grieve your way through parental/separation and divorce to God. It outlines that confusion as one feels love for both parents yet also feels obligated to take sides/peacemake. The only exception I have to it is the tendency to mix the old covenant of sin with the new covenant of grace. The old has been done away with in Christ. The only law that remains is love and the true gospel is peace/joy. This truly glorifies God.
