If this is how they feel, I think they need to say so. They are working through something. their feelings change, just like ours, we come here mad, sad, resigned, weak etc. I have to say that I think the first post is upsetting because it is true.
I think whenever we leave or kick them out, wether they receive it or not, They need to know that they are loved. Leaving does not mean that you stop loving, it means you are going to take that last thread of love to save yourself. This is why I highly recommend no contact for a period of time. They know that they must have no contact with the thing that is hurting them and sometimes so do we.
