This is a pretty sensitive subject, but I've been debating on asking in the first place. So, I've been with my fiance for going on 8 years in August (got engaged in December 2018), and my mother has never really liked him (she likes my ex husband better). When I was proposed to, she never said anything or even congratulated which I wasn't surprised in the slightest. Since I was in my young teen years, my whole family feels she has serious bipolar disorder. So fast forward to today, she still won't be a part of any planning much less ask how things are going which is still not abnormal for me. My only problem is that she clearly stated that she will not attend the wedding in any way. I spoke with my aunt and she said that she will attend, So, my question is should I wait and hope she will attend or have a back up mom (I have a few moms that have taken care of me due to everyone thinking she does have a mental illness?
