Thanks for the comment. It can be difficult for someone (men) to make friends after a divorce, especially if you did not maintain individual friends during the marriage. Recently divorced people also may believe that if their marriage failed, they may have trouble making friends - they connect difficulties in one relationship with future relationships.
Men (and women) looking to make friends after divorce should get involved in things they like doing and hope that friendships will follow. Cleaning the park once a month, playing chess at the rec club, or joining a biking group are all activities that people enjoy in and of themselves. If you are doing what you like doing, friendships will follow as you will be a more fun person.
