Curious if this is splitting or not. I have a long term friend. At one point we were very close. At a certain point though I started finding her very annoying, only being able to focus on all of the parts to her personality that irritated me. To the point where when we hang out together I snap at her and get really frustrated.

She is very kind, but sometimes acts too motherly. For some reason I hate this.

On other days though, especially when she is being supportive and I feel like I have no one, I LOVE her. I gushed to her to my therapist one day because of how supported she made me feel and how happy I was to have her in my life.

Do normal people feel this with friendships, or is this a distinct splitting/bpd thing?
