I’ll try & keep it short. Was on the phone to my mum on loudspeaker & my brothers GF was with her. I’d recently upgraded a home appliance and asked my mum if she would like the older appliance. She reminded me she already had it but then immediately asked BGF if HER mum would like it. A woman I’ve never met, my mum has a few times and they get on well. Before I could say anything she quickly said yes of course! It’s not a cheap appliance, £150+ and was recently replaced by the company and I’d used it once before getting the upgrade. My plan was if my mum didn’t want it I’d offer it to my MIL. Now that’s out the window and I feel obliged to give it to BGF for her mum.
Am I just being really unreasonable? My mum has form for things like this. She announced my pregnancy to family members before I got a chance to and cried on my wedding day because she didn’t know my IL’s.
