Hiya H&H:
There's nothing like sitting there and biting your tongue, is there!
Somehow I thought you may understand this....
Ya. I think so. It's a bit like my "I lost my singing voice...." thread, I think.
Did you feel kind of invisible, sitting there, while she went on like that?
I think I might have felt that way in that situation. She ignored you and your husband.

So sorry (((((((((((((H&H))))))))))). It's not at all what we want and expect from a loving mother.
I'm so sorry she's not "normal" and that she's not a loving mother. It seems obvious but so painful to digest. It's just not what children, even adult children, want from their mother (I bet.....usually).
So......it seems there is definately something wrong.......with HER.
Not you (((((((H&H)))))) (in case those kinds of thoughts are crossing your mind). It's not you she doesn't love or behave motherly to. It's not your brother she loves and behaves motherly to. She's not behaving loving or motherly. She's behaving like a weirdo.....like someone who is chatting with her buddy.......not her son and like someone who's ignoring a playmate, not her daughter. Kind of the way a six year old behaves eh?
Anyway.......maybe the way to get past her behaviour is to consider that she is not "normal" and think that there is "something wrong with her".
It's not easy either, but eventually possible, I hope. That way, when she does stuff like this in future.......
if you were to think: "She's not normal. There's something wrong with her.".......it might help to deflect the rest of the stuff that goes through your head and the feelings that develop after that?
Ofcourse.......that does nothing to ease your longing for a loving, caring, interested, validating mother but at least......it might help stop adding more pain ontop of that longing.
It's a bit like expecting a lion to act like a pussy cat. It isn't going to happen. And if we aren't real careful......we'll get eaten up!! Devoured by emotional pain. But if we recognize that lions will always act like lions and that we must be very careful to protect ourselves from them......things will go smoother and we'll be much safer.
