So, my husband thinks his family is normal, but I am not so sure. He and his brother, his only sibling, barely communicate. When they do, they don't speak for long. I know this bothers him when he sees how my family interacts, but he thinks it is normal because it just is how his brother is with him. My siblings and I speak at least a couple times a week and are much more involved in each other's lives. His brother, his wife and their two children live a three hour trip away from us and we have not seen any of them since last Christmas and then only briefly. They have not visited my husband's parents since then either. I have seen my siblings more and they live an ocean away. Last time we went to visit his brother and his wife after they had expressly invited us, they told us they were busy when we got there and would see us in the next day or so. We had booked a hotel in the area so we could see them for a bit. We ended up exploring the area, but that is not why we came there. We saw them for a couple hours total out of a four day trip after being there two days first. We had our first child this past November. The week he was born they said they were coming to see him. Then they cancelled. Then they said they said they would come in a couple weeks. They cancelled that too. Then this Christmas they cancelled using covid as an excuse. Now they finally arrived in town and are staying with my in laws. We offered to come see them there, but they said no it would unsettle the children. They would come see us the morning after they got in.Then they changed plans and said they would come the next day.Then they cancelled and said they would come today. Now I find from MIL that they decided to go shopping and will come to our house tomorrow. AIBU thinking this is weird and annoying and for being a bit upset at their flakiness? The weird thing is my SIL texts me all the time and comes up with all these ideas of things we should go do together. I have learned over the years to believe nothing she says. It just all is quite strange.
