Congrats bro. If you're a good person, and you know in your heart you want to love and ake care of this new family you have, then nothing will ever change your life like this will. The biggest blessing you'll ever know.
best advice i can give you is this:
1 corinthians 13:11- When I was a child, I spoke like a child, thought like a child, and reasoned like a child. When I became a man, I gave up my childish ways.
