I had a similar friend. There was the possessiveness and excessive concern. I would set boundaries, it would scare her, and she’d break them. We deserve to have friends that respect our boundaries. I actually think the “excessive concern” they have is not for our well being but actually a concern to get reassurance that they have their foot in the relationship still. So I find it not caring at all. I ended up having to state that I was pretty unhappy with things and I just stopped communication. She did initially make attempts to reach out, apologized, then slowly faded in the attempts, but I had to remain consistent because it was like she was looking to open up that door of no boundaries again.

“Honestly, i want to be away from her and maintain as much distance as possible till i feel normal around her ”

It’s good to know what you want. You have a right to boundaries. You don’t have to be everyone’s agony aunt, (I like that phrase).

If I am totally off base ignore me please. But, as another agony aunt, in recovery, I wonder is there maybe a substance abuse issue here. You might check out Al Anon. I for one was astonished that we are a whole species of servers raised to deal with the pain and general crazy of others. If it’s not for you that’s fine, they have some good literature too.

I believe it was Conversations With God, i’m not sure but, somewhere I heard, “now you crave, solitude, that’s good” Now you can want your own company and your own accomplishments. I give you permission. ; )

“To be happy, we must not be too concerned with others.”
