guilt is like shit, flush it away

That is what my therapist told me. I said this to BPD and he is still trying to push my guilt buttons. I picked up the kids today and didn't go out of my way to make sure I saw him. After we left he called me and said is this the way its gonna be? I was in the house for 20 minutes talking to the kids while they gathered up their stuff to bring to my home. One of the kids didn't even know where he was in the house. You can hear the door from the garage into the house open and close. If he couldn't tear himself away from the television why should I bother to go searching for him. Do I feel guilty?? Not in the least. Its shit and I have flushed it away!
