When I read this post, It sounded just like our daughter age 34. We stood by the laws of God. It was difficult. She begged us to accept this man she was living with. His parents accept me, she would say. I, mom, was the one who would speak to her. I answered, we do not accept living together in sin. They are wrong to accept. This man is not available to you. Also, IF he decides to go back to his wife, or her to him, you daughter are in the way. God believes in forgiveness of sin.
It happened. His dad died and left him money and he left our daughter and took all he could. What is more sad, our daughter has a daughter from a previous man, and she is age 12. We, the grandparents were able to baptize her with their permission.
Now our daughter is in agony. She asked for a little help. She needed a loan towards her car and we signed($6,000) with her keeping the loan paid. She is 2 classes away from RN. We asked her to keep a promise, to come to Mass at least twice a month and say 3 Hail Mary's every day. She turned her back against God at age 18 with drugs. Then she got out of that. A blessing and yet she continued like Mary Magdalene which is the name she took at Confirmation.
So far so good. We continue to pray and she is showing some growing up.
Yes, we parents have many tears like St. Monica. You must stay strong to God's Laws. Never back down. God Bless you!
