If you are retiring without a companion you are not necessarily doomed to bingo and mahjongg for the rest of your life. Dating after 50 is a bit different but it’s there. First..try a new activity..cooking, hiking..volunteering. You’ll meet people. Look up old friends who may be in the same situation. And yes, you can go on line to one of those dating services. But be honest and don’t turn the first date into a job interview.
