Well I haven't even been married a full year yet but I can say something that has helped my wife and I was her quitting her job and becoming a homemaker. I can focus more on my job while she can do the household chores that I hate and read up on Christian parenting books. We pray together in the evening and before meals.
Before covid, conflict with parents and in-laws would typically come from how you want to raise their grandkids (we will home school which causes conflict) as well as religious and political issues. My wife and I already disagreed with our parents and in laws on these topics but now there is a new division in families - your stance on covid and vaccinations. This division also impacts friendships, so newlywed life in the age of covid has seen us lose relationships with family and friends. Your task as the head of the household is to negotiate these landmines and not to give in and to reassure your wife.
@Eusebius Erasmus I empathize with you on this one although my situation isn't nearly as bad.
Being Orthodox and finding friends can be tough - it's a very niche interest in America. When most guys talk about sports or trucks I just have to sit there silent and nod along.
A big question for new couples is where you want to ride out the societal decline. I would like to live close to one of the parishes that never closed, but due to my local governments and lack of ROCOR parishes nearby that is hard to find.
