My 12yo son wants to stay at dads

I divorced my ex when my son was just a toddler. it was amicable and we aimed to make everything fair. Time between our homes were split down the middle of the week(3 days plus everyother sunday). Ive always lived on my own and then eventually with my now husband and two little ones. While my son's dad remained at his childhood home with his parents. My son's grandfather is a sick man and needs to do dialysis in a hospital setting 3 times a week.Last year was challenging for everyone. I was making sure our household was safe knowing if we were to transmit anything through my son, grandpa would have a very hard time. We were still alternating visits until December. When my son came for his turn at my home when I got the call from his dad saying the grandpa tested positive for covid. I was scared. I had a newborn and a toddler. My son left with his father after spending the day with us. My husband tested negative. My son and ex tested negative and quarantined for two weeks. Then their second test, just after new years, was positive. To say the least my son was at his dads until March. I consulted with my doctor and he gave the greenlight for my son to come back home saying he has immunity for a few months. My husband prefers an extended rotation, one month between households. My ex(not willing to change at all) and I temporarily changed the schedule to a weekly visit (I was hoping to compromise at 2 weeks).Now the numbers are going up in my city and surrounding areas and my husband is saying one month rotation or none at all.I've spoken to my son about staying here for a month and he doesn't want to change the schedule. At first he said even two weeks would have been too long. He says he doesn't mind and would rather stay at his dad's. He says he likes it better there. More electronics and later bedtimes. Even though I have the two little ones, I always included him as much as I can. Doing activities here and there like baking, video games, board and card games.Ive been trying to explain that our house would be safer for him but he still wants to stay with dad. I told him that if he chooses to go to his dad's come the end of this turn he might have to stay much longer than intended. He wants to stay until end of August. I feel like I'm losing him. I want him to be safe and I know that because we are doing everything we can to remain so. I don't know why I'm posting this. To vent I guess. via /r/Parenting https://ift.tt/3tVneKu
