Son hates seeing his dad..

Idk where to post this but I feel really torn, I literally CANNOT stand to see my sons dad take him. My son has a melt down, kicks, screams, runs away, grabbing me.. if we are all together anytime I walk away from my son he starts screaming, he pushes his dad away. I really don’t know what to do, it’s starting to become uncomfortable seeing them together... I don’t know what to do, or if it’s normal 🤷🏻‍♀️
