Deeper Meaning: Forever My Girl

What does this romantic drama film tell us about forgiveness, pity and reconciliation with those who have hurt us and put us through a lot? Not only does this beautiful story tell us about how a guy who walked out on a girl on their wedding day (didn't even show up), didn't even know he had a daughter and through coming back was truly able to love his family, but also gives us great character development and an interesting parallel I picked up on between this film and Finding You. What lesson does Forever My Girl give us to reflect on?
