I don't want to reconnect with an ex-friend who keeps messaging me right now.
Why didn't you want to reconnect?
I'm going to stay away from her becuase I think she would fuck up my life.
It makes sense that you would want to avoid toxic relationships.    I would assess what was good and bad about the friendship and make a decision that is best for yourself to avoid an unhappy situation.
You are being a dick about it. You don't see my point of view.
No I am agreeing with you. You shouldn't have to reconnect if you don't want to do it.
