Thanks all of you who posted thoughts on recent thread. In the end, SIL attended our wedding this weekend. She stared out of the window as we took our vows and ignored me all day. I was OK until she walked past me and a friend and as I said Hi to her she stepped over my dress and blanked me. DH was extremely angry but didnt want a scene. MIL was unaware but probably because she didnt speak to us much either. Just kept staring at SIL with sad expression. Eventually as the evening went on (i wasnt drinking by the way) I became so upset I ended up crying with my maids of honour. Thankfully I managed to act as normal in front of most guests, although one of my family members witnessed me telling DH what had happened. When DH spoke to his brother about situation he merely said 'atleast she came I didnt think she would, she's just upset about Dad'. What can I say to that? Ultimately, she marred my wedding day, which makes me furious, and so sad. I want nothing to do with her again but as she lives with MIL I will see her whenever I take kids over. AIBU??????
