Time for an Introduction...and Thanks

[figure-it-out]

Hi Brian,
How was the hockey game?? What an AWESOME ex MIL! A whole pan!!

The kids and I went to breakfast with my parents on Thanksgiving morning. D had to work that afternoon. After she got off work we went to MIL's house. H wasn't there. He had told me he wouldn't be. S was upset and cried when he found out.

I have to admit I was a bit taken aback and am not sure how to react/respond to the following. Maybe you (or someone else) can advise.

There was NO mention of H at all on Thanksgiving. I assumed his mom must have spoken to him and found out he wasn't coming. The next day when we were out driving around S casually mentioned that my 9 year old nephew had told him about how he and my BIL had gone over to dad's "place" to help move a TV.
That made me really upset. I didn't let on to S. I am angry that no one from H's family has even let on to me they know of H's living situation. Clearly his mom knew he wasn't living with her anymore but to have them actually know where his place is, etc. and not say anything to me is really affecting me. His sister has always said she feels closer to me than H because of his personality, etc. and knows I would be there at the drop of a hat for any one of them.
I guess this situation just brings to light how inaccurate her previous statements really were but it's really hurting me.
Granted, I don't know the whole situation. Maybe GF wasn't there when BIL went over, maybe H told him he was living with a "friend", who knows but to not say ANYTHING to me...
Maybe I'm making too much of this and clearly it's something I need to discuss with my therapist tonight. I'm just thrown a little bit.

Enough rambling for now. I'll journal tomorrow what my therapist has to say.
