Would it be helpful to you to know he did?

I understand though what you have gone through being the family scapegoat. I too had a bully of a mother who blamed everything ill that happened or was wrong with her life on me. I had done so on purpose or willed it to happen. And yes, favouritism existed.

What do you think may be the reason?

In my case I have done the math and it is obvious mom regretted my unplanned arrival. She openly reminded my father and I she wasn't living the life she was destined to live.

So I ask what may have been the trigger and suggest that might be a starting point in having a heart to heart with her (something I wish I had done before my mother passed).
