I got remarried five years ago. My wife has three sons who went to or are currently going to Arizona State. It was never an issue until ASU joined the conference. The Big 12 Championship game was tough, but we all went to the ASU basketball game, so we're even. (Kind of, considering the football game had more on the line.) I also have two sons of my own with degrees from ASU, but I brainwashed them to be Cyclone fans from birth so they are split on their allegiances. I think they root for whichever team is better. (ASU for football and baseball, ISU for basketball.) I root for ASU when they aren't playing ISU, and I'm a big ASU baseball fan since ISU doesn't have a team and my son played on ASU.
