Married couples need friends too, not single friends, but other couples to interact with. Finding these types of friends, and retaining them, can seem a little more daunting than just making friends with one person. The best way to accomplish this task is to start out using a variety of places such as parks, fitness classes or online to find potential couples, introduce yourselves and following this ask questions to get to know your new friends and see if their values and interests mesh with yours well enough that spending time together will be enjoyable for everyone.
