Dear Abby: I had good reason to cut off friend but still feel guilty

DEAR ABBY: I had a close friend, “Kayleigh,” for about 10 years. She helped me through tough times and was always there for me. Now I feel like she has turned into someone else. For the last six months, she has been putting down everyone I love, even in front of my daughter. She sees no problem with it, nor does she have any remorse.

Kayleigh doesn’t have a healthy relationship with her family or in her love life. I believe I’m her only friend. When she does this, I feel like she’s disrespecting me. I have talked to her about it, but she never apologizes. She gets defensive and says it’s “just her opinion, it shouldn’t matter and I shouldn’t stay mad.”
