At the start of December 22 of my husband and I experienced a life threatening crisis which is ongoing with my FIL. He was admitted to a Hospital 2 hrs away which he remains to this day. I only have my brother and SIL nearby. I asked my brother and SIL if they would be able to have my 12 yr old son over a couple of times during the 6 weeks of school holidays as he would be home alone a lot. Since we needed to be at hospital, work and husband working too (my husband could only get one week off due to shortages and I was the only staff in My office over the break due others on leave and sick with COVID) I called and explained the situation to both of them, called In personally and messaged. They didn’t offer to help out so I thought I would directly ask them. They have a son the same age and they get on well and both enjoy biking. When I asked them both if my son could come over a couple of time they replied they they would see what they have on and get back to me. That was 7 weeks ago and I have had no contact from then since (apart from Xmas day gathering) not even to ask how FIL is. On Xmas day as a group we were talking and they knew that my son would be home alone on 28/12 and they in this conversation they said they had nothing on but instead of asking if my son would like to come over they invited my cousin over for drinks. They have been quite cold and rude multiple times over the years. Am I overreacting by being angry?
