Here's a problem I've had in a lot of my relationships:
Sometimes when we get together, I feel like you want to connect with me and get close.
Sometimes when we get together, I feel like you are shutting me out.
I enjoy getting together with you under the first circumstance and I do not enjoy getting together under the second circumstance.
I know that a lot of the time you tell me you need to be alone. And that's ok, because I prefer for you to tell me you need to be alone, then to be with you and yet feel very alone myself.
