Has anyone truly understood the many nuances of relationships and navigated them successfully? I would venture to say no one. Mother, daughter, father, son--I would still say none.
Keep in mind that a man and a woman or a romantic relationship seems to be the most problematic. Everyone wants to be loved, but receiving and giving love are two completely different things. The heart is a delicate thing; in the wrong hands, a heart can be torn to pieces.
This book can both help and save you from heartache and pain. Just trust in God's Word and guidance. You'll find peace, love, and joy when you lean on and depend on God's guidance.
Unfortunately, there are too many who don't believe in or know much about God. They amble alone, doing harm and leaving brokenness in their path. Don't be a victim anymore. Just be wise enough to learn from past mistakes. Read, apply, be loved, receive love, and be happy!
