I don't want to speak to my extended family
Is there something that bothers you about them?
They give me too much attention and I find it annoying.
It's okay if you don't like the fact that it feels like they're smothering you, but you can still keep in touch with them on occasion.
You are right. I should be a loyal friend to my family and stay in touch but just try to set better boundaries in our interactions.
That is a good trait to have, and I think that you should just try to keep in touch the best that you can. It is not okay for you to exclude your family from your life.
