If you are a Christian and have a little knowledge of God's word,
Remember this: If you have a mutual understanding with each other; in God's eyes you will be married. Especially if you have intercourse with each other. Especially now and you have a child. You have the ultimate responsibility for each other and to your child.
TRIVIA:
And in the Bible, you can not find the word "KASAL", you will find the word "PAGTATALI" OR BIND in English...
