...... after their wedding last Saturday?
Background of relationship with SIL:
here
Neither db nor sil introduced me to any of their friends or family at the wedding. And my elderly mum, who's a very recent widow. was left sitting alone in the reception venue until she just gave up and went home. She did introduce herself to SIL's sisters before we moved to the reception venue, but that was done on her initiative. The reception was held in a pub and was very informal, but my mum is 75, walks with a stick and shouldn't have been left sitting alone while SIL's family (who we hadn't met before) all clustered together on another table.
SIL barely acknowledged me or my mum the whole day and ignored the children as usual.
I'm feeling so sad and angry with my brother for allowing this to happen. He doesn't know SIL's family that well, but he could have made more of an effort, as could she, to have acknowledged me, my sister and my mum as part of the family.
