<human>: My fiance and I have been dating for 3 years and been engaged for a little under 1 year. Before getting engaged, I talked to her dad quite a bit about our plans to get married, and despite raising some valid concerns (mainly if I would have money to provide for her daughter seeing as I am a teacher) he said he was okay with marriage.

Throughout the following year, I try to get to know my fiance's family better by doing things like inviting them to dinner, giving gifts for their other children's birthday's and eventually I get to know most of the family (2 young sisters, and a high school aged brother) pretty well, with the exception being the mother who seems to avoid me at all cost. 

For a while, I thought she was just nervous or intimidated, as I am a large black guy in a predominately white area. But as we get closer and closer to the marriage date, her mom has informed my fiance she is "making the worst mistake of her life" marrying me and that she would not come to the ceremony if she follows through with it.

I was kind of taken back by this, as I thought the relationship I had with my fiance's family was going well. We later find out through the grandma that the reason the mother is so opposed to the marriage is because I am black, and she believes black fathers are unreliable partners.

I really don't know how to respond to this at all, and this is really eating at my fiance and I. How do I deal with situation? I'd rather not burn bridges with the family but I'm not seeing how this ends well.

Give me a shortened version of the text
<bot>: Future mother-in-law refuses to attend the marriage ceremony because her daughter is marring a black person. Not sure what to do.
