Dear Abby: I have an awkward wedding conundrum I hope you can help me with. I am getting married in April and want to invite two co-workers with whom I am very close. One of them is married; the other, “Sara,” is in the process of divorcing her husband. Sara was unhappy for years with her almost ex-husband, and we witnessed the deterioration of their marriage over several years.
About a year ago, while still married, Sara began an affair. She’s still “seeing” this man — sneaking out, meeting him on his lunch break, going to motels — while she goes through the divorce process. She considers them to have been a couple for the past year.
