About your question to me, it can be because of his needs but it doesn't mean he has to be blamed for but if that makes it work for you, so be it.
I think always needing to place blame on the outside keeps us from looking inside. We shouldn't "blame" ourselves in a masochistic kind of way but rather take these moments as opportunities and ask what am I supposed to learn here.
Have you read the driving post I wrote on Maybell's thread? I think it relates to this discussion.

Let me give up the need to know why things happen as they do. I will never know and constant wondering is constant suffering. Caroline Myss
