I've booked wedding with new partner. Its this sunday. He has just told me his ex says she wants to see dcs as its mothers day. I had no idea that it clashes with mothers day until last month when she brought it up. Its still not resolved. Ex normally sees her dcs on mothers day. She has asked us to rearrange wedding. I think oh's ex is being unreasonable and we have offered her another day to have dcs as we want them to be at wedding.
I don't know who is being unreasonable.
