Bit of background so as not to drip feed; DH and his brother had a terrible relationship as teens but are much closer now, they socialise once a month or so and I have a good relationship with BiL. I was very close to his ex, she was a bridesmaid at our wedding and doting auntie to our kids, we haven’t seen each other in person for a few years now but still speak on social media.
BiL split with his ex after she caught him cheating with the woman he is now with. She found out in (in my opinion) one of the worst ways, as she found an earring in their bed that belonged to the other woman.
Fast forward 3 years and BiL is now engaged to said woman and getting married early next year. I’ve made an awful lot of effort to get to know FSiL and to have a good relationship, but she’s quite… difficult. (Other family members including MiL have also said this, so not just me.) She’s very hot and cold; she can be very chatty and friendly one day and then totally blank someone the next; a prime example is at our DD’s birthday party earlier this year she spoke not a single word to me or my parents despite it being held at their house and our attempts to engage her in conversation, yet the week before we went to a concert together with partners and she was very chatty. When they got engaged we found out that they had gone out for a meal and drinks to celebrate with her sisters and friends, but we hadn’t been invited as “they didn’t think we’d be able to sort a sitter.” BiL looked very sheepish when we found out and it did upset me. I’ve now found out that I haven’t been invited to the hen party (DH has been invited on the stag but won’t be going as it’s abroad, he has made separate arrangements with BiL and FiL) and it’s made me feel quite upset, and like I don’t want to attend the wedding. I know I’m probably BU, but I’m really quite hurt. Would you feel the same?
