Is it adultery to marry again?

Question:

Good day;

I have read your articles on your website and I find them very edifying. I have a couple of questions, and I hope you can help me.

I became a Christian and was baptized at age 17. I was pregnant, and my mom had just become a Christian a year before, and she invited me to her church. That same day, I accepted Jesus. She kind of forced me to marry the father of my baby. He was very abusive, and I divorced him after two years. By then, I was not attending church as much, and I fell into sin.

I prayed to meet a godly man who would help me get closer to God. Five years later, I met my second husband. His family had been Christians all their lives. We were married, started attending church, and we served the Lord as best we could. He sang worship and evangelized. Throughout the marriage, we slowly stopped attending church, our prayer life was slowly decreasing, and one day, we both fell into adultery. After 20 years, we divorced. We fell back into our old ways. He now has a new life and a baby on the way. And I was lost in sin for four years.

I met a person and lived with him for two years. I started to feel shame, and I wanted to get right with God. I have repented and asked God to forgive me for straying so much. Six months ago, I moved out of the home I shared with this person because I did not want to live in fornication. I do not want to sin anymore; we were engaged to be married, but someone told me that I can never remarry again because it would be adultery. I want to live my life right and never want to live without God ever.

I am very depressed since I left. My ex-fiancé is also suffering because I abandoned him, but I did it because I thought it was the right thing, since I was told marriage was not possible. My heart is broken. And I pray and pray that God restores and forgives me. For the past six months, I have been trying to live a holy life. But no matter how much I pray or fast, I can't feel God's forgiveness, I can't feel His presence, and I cry so much. I live tormented by guilt and shame, and I regret so, so much straying from the path. I cry when I think of how I hurt the Lord with my sin. I wish I could take back all those years. I am always anxious and I can't hardly sleep. I want to ask: Can I be forgiven? According to the Bible, is it adultery if I marry again? Do I have to remain single?

Please help me. All I want is to be faithful to God and truly be obedient to His word, as I was meant to be. I realize I never really submitted my life to the Lord, and now I don't want to make a mistake again. I don't want to do anything that goes against the word of God. I want to be obedient and able to do God's will, living according to His word.

Thank you.
