How is this even a complicated questions. Facebook is a way to stay in touch with friends. Add your friends. Since she is not your friend, don’t add her. If you have mutual friends, you can add them and it doesn’t mean you need to add her. I can’t believe I actually had to type this out. The boomers on this board make my head spin.
I imagine it’s tempting to have access to her updates, but where’ll that get you?
Don’t friend her, and don’t accept her friend request, if one should appear.
The big rule is, when someone does little (or big) things to make you happy and make you feel good, then that is a relationship worth building.
When the opposite is true, let any remaining affection die.
Do not build or resurrect a relationship with someone who isn’t doing things (currently) to make you laugh or to make your life richer. Right?
Some people do a crappy job of cutting ties. Someone can reject them or neglect them in small or large ways, and they stay stuck in thinking they should try to keep that person or win back that person.
I think it is good to like people ONLY who are being likeable and being endearing. Otherwise, withdraw your affection, to deploy it elsewhere.
This has to be troll thread
