My mom convinced me that if I invited my uncle's ex wife to the wedding it would make several people uncomfortable. Most of the family feels she abandoned my uncle, but I'm not sure I agree. I haven't had much contact with her since they divorced. I reluctantly went with my mom, but did invite all her kids. Now my uncle isn't even coming and my ex-aunt (??) sent me a Facebook message saying my cousin told her we were getting married this month and best of wishes. I didn't know what to say but thanks. I felt like I should explain but I didn't.
