Ignore ,ignore,ignore .......wash ,rinse ,repeat ..... You are probably right that they are coming by because the CO visit is close . Things will go back to off the radar after his visit is over is my guess.
If they do run into you in public and ask to come by for an encouraging call .....DO NOT ACCEPT ......I made that mistake . Just thank them for their concern and let them know you will call if you need anything .
Just a heads up if you don't want to go back then don't let them back in your life even for a minute .
Always remember your personal life does not need to be open to those you do not choose to discuss it with . It really is YOUR choice.
