Kristen Hayes, the widow of former NFL player Jimmy Hayes, shared a heartfelt message on Tuesday following her husband’s sudden death.

Jimmy Hayes was found dead on Monday in his Boston home, just months after the birth of his son.

Kristen shared an Instagram story of the couple with their two sons, 2-year-old Beau and 3-month-old Mac.

“My angel I love you so much,” she wrote. “I miss you. I don’t know how I’m going to do life without you. You should be here. This isn’t fair.”

Philadelphia Flyers centerman Kevin Hayes, Jimmy’s brother, also posted a tribute on Instagram on Tuesday.

“Yesterday I lost my best friend, my brother,” he captioned a picture of him with Jimmy. “My whole life it has always been Jimmy and Kevin or the Hayes brothers. I have followed you around since I can remember and I wouldn’t want it any other way. Whether it was youth hockey, Nobles, Boston College or the NHL, you paved the way for me. You taught me everything I needed to know in order to succeed. You lit up every single room you walked into with your smile and positive attitude.

“Everyone wanted to be around Jim, the big, goofy, horrible dancer, funny, genuine and kindest person around,” the caption continued. “I will never forget the times we shared or the memories we made and know that I will try my hardest to have your legacy live on. Our world lost someone special and I don’t know if I will ever be the same but till we meet again, I LOVE YOU JIM!”

Jimmy was drafted by the Toronto Maple Leafs in the second round of the NHL draft in 2008. He later played for the Chicago Blackhawks, Florida Panthers, Boston Bruins, and New Jersey Devils.
