That's sad. Sorry to hear it. Maybe in the process of working so much to provide, there wasn't enough time for bonding and quality time? IDK I hope you can find a way to restore the relationship
NO MATTER HOW MUCH YOUR KID HATES YOU, DISOWN YOU, AND SAYS YOU WILL NEVER SEE YOUR GRANDKIDS, THERE ARE STILL SLEEPLESS NIGHTS THAT YOU SIT AND THINK ABOUT THEM. IT’S 1:00 IN THE MORNING AND I LAY HERE AND WONDER WHERE I WENT WRONG AS A PARENT. I GAVE EVERYTHING, I WORKED HUNDREDS OF HOURS OF OVERTIME TO PROVIDE AND MAKE SURE THEY NEVER MISSED OUT ON ANYTHING BECAUSE OF MONEY AND YET ALL OF THAT WAS NOT ENOUGH. I WISH YOU THE BEST.
