A: No, you shouldn’t feel this way. You had no control over their decision, and you shouldn’t feel guilty because they chose to stay together on your account.
In fact, you should be grateful for their love for you, and their willingness to sacrifice their own happiness to help raise you, in spite of their difficulties.
It would have been far better, of course, if your parents had been able — with God’s help — to resolve their conflicts and heal their marriage.
Pray for your parents, and let them know you love them in spite of what’s happening. And pray for yourselves also, that you may learn from their mistakes and build your own marriages on a strong foundation — a foundation based on Christ and his love. God gave marriage to us, and when we commit our lives to Christ and seek his will in our marriages, we can discover the happiness and security that he intended for us to have.
