I had that situation with my older brother. We didn’t talk for like 5 years. It was his doing/choice, but I was indifferent about it. Then one day out of the blue he called me and was like “hey, it’s been a while. Let’s bury it and move on”. I literally almost fell off my ladder.
This time it’s my younger brother. For some reason (I’ve never heard the actual reason), he hates my wife. It’s gotten to the point where he won’t even acknowledge she exists, unless it’s to blow up at her. My middle daughter is turning eights and getting baptized in two weeks. I didn’t invite him to the baptism and my parents are losing their **** on me. They’re telling I’m starting a war in the family and stupidity like that. When I bring up they way he treats my wife and kids (always short and snappy with them, if he speaks to them at all) they tell me we need to be the bigger people. I’m done being the better person with him. It lasts for a year or so, then he blows up again. I’m done with that *******.
