Well done. Yes, we start setting boundaries, "friends" disappear. That is a good thing. They were not true friends. That opens us up for the possibility of making new friends who are real friends. Ones that will honour, respect and cherish us. People that will respect our boundaries and set the same kinds for themselves. These friends are most likely open to being confronted and open to confronting us on our own shit too. Those are real friendships. That is what makes real relationships too! Well done. You took a big step my friend in recognizing that violence is not only physical, but also emotional, mental and spiritual. Rare for people to figure that out.
