Namechanged as don't want to be recognised.
MIL sadly died in January. It was a huge shock and really hard. We were all there as she passed away. MIL was a great woman and I really loved her, she did a lot for me and I am so very sad that she is no longer with us. She was incredibly young as well, so it really was a shock.
SIL has planned to do the Race for Life this year in memory of her mum. I think that is a great thing to do, and I told her it was brilliant she was doing that etc.
SIL has since on facebook (work of devil, I know) invited DH's brothers' girlfriends to do the race with her in memory of MIL. These two ladies are very nice, one knew MIL for about 4 months, and the other for a year.
However, SIL has not asked me to do it.
I understand it is her mum and she must do what she feels best. MIL was not my mother and I don't want to step on any toes. But I feel really disappointed that she asked these two to do it with her and not me.
