You’ll drift apart
In the same vein as the previous point, you may try to do some growing later in life. When you and your husband are all set in your routine, you may suddenly have that inevitable strong urge to “find yourself” like all your single friends did and like you never did. You may start taking night classes, or actually going on trips without your husband, or joining any and every type of group in town. You might suddenly panic and wonder “who the hell am I besides this guy’s wife?” and your steps to answer that question could make you and your partner drift apart.
