As said above, my mother in law is just a raging bitch. 

My fiancé and I got engaged relatively fast, and it didn't please her, but we both discussed it with our therapists and the consensus was go for it! 

We announced it to our parents first before posting on Facebook and my family was delighted. 

His father(a raging alcoholic) could give two shits and talked on and on about day trading and his mother. Well, she was disappointed in the the relationship. 

She knew I had been in a long term, very committed relationship before that was physically violent, emotionally unstable, and the man was always gaslighting me and mentally abusive. 

She also knew I have bipolar type two. Which has been controlled and managed for three years by meds and therapy. 

I've also been through some pretty intense self finding therapy for myself for the abuse and spent a year single before dating again. 

So, back to the point, all this woman does is point out my flaws. She has never said one redeeming quality about me. I'm just not good enough. I work a great paying job at a very reputable company in my state, am attending a private university in my state that's in the top 100 in the country. And I'm going for a PhD. None of this wins me brownie points. 

The biggest one is, my fiancé was with an abusive woman for six years and I make him extremely happy. We're both very happy, so wth gives? 

We were planning on eloping and starting a family but she cried about how unfair it was that we didn't have a ceremony and how she hasn't met me. On and on about she is hurt. My dad has met my fiancé and he came out. She hasn't once offered to come see us. 

I'm so angry and hurt. I want nothing to do with her but she is my fiancés mother and I respect that wholly. 

What can I do to let it go?
<bot>: Raging cunt mother in law, can't stand her. Need advice on how to ignore her stupid antics. Thank you in advance.
