I used to think that it was callous of me to avoid her but I'm starting to realize that I'm just trying to protect myself. I don't want to be uncaring towards her or abandon her.
Are you able to see your LC as sufficient for you, regardless of what she may feel or say about it?
It is the same with this:
I know how things are supposed to be between family members.
In these situations we have to determine what is right for us and accept that what is right for the masses may be different. Thankfully they do not have the same experiences as you and are able to have a more traditional relationship with their parent. We are different. I am not trying to make you feel badly here just trying to point out that we can't always use the same metric to measure us or how we choose to interact with our family.
Your dream speaks to me of you not being free to be yourself and be vulnerable with your mom. That says a lot don't you think?
