My bridesmaid has given all the info regarding my wedding abroad to her mum who has now booked flights and accommodation in the wedding city. Her mum was never invited to the wedding which I pointed out at the time she booked the flights. My BM is now putting pressure on me to let her mum come as she will be left alone during the wedding. AIBU not to give in and let her come? I barely know the mum and feel I'm being bullied and emotionally blackmailed by my BM.
