My bil started dating a girl about 3 years ago both are in their early 20s and the youngest in both families… Ashley( not her real name) was lovely to begin with but over time I noticed a slight hostility to me and my dh which gradually increased and spread to dh other siblings and their partners … they are getting married in 3 months and here lies the problems ….my lovely daughter was initially told she was flower girl we said we would pay for her dress etc to help out which we did the dress arrived and Ashley asked to see it on my girl …she looked beautiful and was so happy with the fairy style dress that had been selected by Ashley … 2 days later I get a text from As mother how dare I over dress my brat taking attention away from A and that was not the dress agreed on ….next was a call from my mil followed by all 3 other Sil berating me for spoiling As wedding by picking a totally ott dress for my girl ….now my girl has been removed from the wedding party and I have not been invited to any of the 5 hen parties/ bridal showers … the latest attack happened at a family dinner where dh my girl my 2 sons and myself were torn to shreds by his family …we are snobs we are selfish we think we are special with our big house and fancy cars …we have our own business that we worked our butts off to make successful….I stood up and said that was it we were done with her and her poisonous spite and we all left the problem is we agreed to host her wedding party on our property and I just want to say no get a new venue but dh says that would be descending to her level and we should be the bigger people …AIBU if i want us to descend to that level
