Planning for the future is also a great topic. It could be about saving for a big purchase like a house, or discussing how to raise children in a healthy and positive environment. These topics are much more positive and conducive to a happy married life.
One proper topic is how to communicate effectively in a marriage. Couples need to listen to each other, express their feelings and thoughts clearly, and avoid misunderstandings. For example, setting aside a specific time each week for a 'couple talk' can strengthen the bond.
Another topic could be about shared hobbies. If both the husband and wife like cooking, they can explore new recipes together, or if they like reading, they can start a book club for two. This not only enriches their time together but also deepens their connection.
