You are so right. I don't know the whole story ... your story. But this story repeats itself thousands of times through the years, with you, with me, with everybody. Anytime we decide to deviate from God's law, we have to pay consequences.
If Matt had not been having illicit (as far as God's word is concerned) sex, he also would not be in the situation he is in. I am not excusing myself, as I am not perfect and we do commit mistakes. That is why I know that deviating, even by fractions, from God's law will cost us in one way or another.
That woman really had no right to take you to court, demand back support, and then kidnap your child. I'm sure she is also paying in some way, or will pay in some way. I hope yuo can get this resolved, for your own peace of mind.
Having said, that, your story is in no way like Matt's. He is refusing to accept this child because he didn't plan for it. That child is here now, and she is a beautiful child. If she can't melt his icy heart, nothing can.
