Fiancés jealous friend?

A female friend of my fiancé's who I never liked and she never liked me basically ended the friendship with him because I got furious with her when he lied to me about hanging out with her one time. In this message she said I cannot come to your wedding (we never invited her) because I can't watch you marry someone who doesn't make you happy.

I'm furious about this comment and don't know how to take it. My fiance came back and said actually I do love her and am excited to be a husband.

She doesnt even know me or our relationship but those words hurt and cut deep.
