This is an english assignment and i need help on commas please

Kevin was a man that no one can replace...at least not in my life and most importantly in my heart. We have been married for 15 years. Yes, not all those 15 years were happy. What we had was not a perfect marriage but people say Kevin and I are perfect for each other and we were! I remember back in high school when we first met. I was the cheerleader and he was, lets just say, the nerd. Are groups of friends were different and we did not interact. One day I was crying in the hallway about typical high school drama when Kevin was the only one who approached me and comforted me. From that day on we became friends and I was the cheerleader dating the nerd. This showed a lot about Kevin's character. He was always compassionate to everyone, even strangers. As you all know Kevin was a jokester, always made people laugh, and loved the beach. He was always at the beach. Whether he was surfing or just thinking, it relaxed him. I will never forget the day Kevin brought me to his special spot there. It was the place where he could clear his mind, his place. He had never taken anyone there and he was acting all serious and nervous which we all know he rarely does. After Kevin settled down his nerves we laughed and talked for hours in his old MG-Rover truck. We watched the sun set and he asked the very important question. I left the beach that day as bride to be. Yes, I fell for the nerd. Kevin never really wanted children and when I did get pregnant Kevin was my number one supporter and turned into a family man that very day. Our five-year-old daughter Kelly was the light of Kevin's life. He was a proud father. I know he is bragging to everyone in heaven about her and will always be our protector. I have yet to realize why God took a great man, a husband, a father, and such a young life so soon. But I do understand that Kevin would not want his friends and family to sit and mourn but to remember the good times. Remember his jokes, his laugh, his smile, and his love that would just radiate off him. Every time you are at the beach feel his warmth on you. Honey, I love you, and I will be seeing you again some day, I am sure of that.
