I'm someone who completely hates rejection and confrontation. If I know someone has an issue with me my initial reaction is to back off and withdraw. I become really guarded and just don't want much to do with that person. I am not mean or anything like that but avoid/ keep my distance/ don't really talk to them. This has happened to me with someone.
Looking at it, it's probably not a good idea to be like this and the best course of action is to still be friendly and chatty with them.
It's been a long time now I don't know if the relationship can be salvaged. I don't want to be bear friends or anything but don't want to carry on like this.
