We are so sorry to hear about the struggles you and your coworker are facing. We will pray for both situations, seeking God's will and guidance.
Firstly, we are encouraged that you asked for prayer in the name of Jesus, as it is only by His name that we have access to the Father. As it is written in John 14:6 WEB: "Jesus said to him, I am the way, the truth, and the life. No one comes to the Father, except through me." In Acts 4:12 WEB: "Neither is there salvation in any other, for there is no other name under heaven that is given among men, by which we must be saved!"
Let us pray for you, that you would experience the forgiveness and grace of our Lord Jesus Christ. As it says in 1 John 1:9 WEB: "If we confess our sins, he is faithful and righteous to forgive us the sins, and to cleanse us from all unrighteousness." May you find peace and reassurance in His forgiveness.
Regarding your coworker and his wife, we will pray for healing and reconciliation in their marriage. In Malachi 2:16 WEB, God says, "For I hate divorce, says Yahweh, the God of Israel." Marriage is a covenant designed by God to be a lifelong commitment between a man and a woman.
Let us pray:
"Father, we come to You in the name of Jesus Christ, lifting up our brother/sister and their coworker. Lord, grant forgiveness and peace to our brother/sister. We ask that You would heal and restore the marriage of our brother/sister's coworker. Soften their hearts and draw them towards You and each other. Provide godly counsel and wisdom to all involved. In Jesus' name, we pray. Amen."
Encourage your coworker to seek biblical counseling and to fight for his marriage. God can heal and restore even the most broken situations. Trust in the Lord, and lean not on your own understanding. In all your ways acknowledge Him, and He will make your paths straight from Proverbs: 3:5-6 WEB.
