Am I over reacting?? Basically my partners mother & his sister wanted to plan my baby shower ( which is tomorrow ) So his mum said she would get everything like the cake decorations food etc.. so my mum offered to pay half as my partners mother said it would probably come to about £35-40 max each.. baring in mind the venue was free. My partners mother text me 2 days ago asking if it was still ok for my mum to go half and asked if my dad would aswell ( when my mum and dad aren't together & my dad isn't even going!!) and she asked for £40 off my mum & £40 off my dad.. so I thought that she must have spent £80 herself and then just wanted my family to pay the other £80.. my cake is £35 which I think is crazy price.. besides the point me and my partners sister was talking about it yesterday and I said " your mothers spent a lot on the baby shower" and she said " I know you know what she's like she goes over the top.. she's using your mums £40 for the cake & pack of balloons and your dads £40 for the food & then she's spent £40 on decorations & bits and bobs" so that basically means she's spent £40 and my family have to spend £80??? I'm not really happy with it as she insisted that she planned the baby shower and that it was only going to be £35 off my mother.. I don't really think it's fair to be honest as my partners coming to the baby shower so it's just as much my baby shower as it is her sons?? Personally I think she should have asked before she spent!!? Am I over reacting?!
