My fiance proposed on Sunday night and I say yes. When my mother learned of this, she became extremely upset about this and told me over email that she doesn't want me to get married because she didn't want me to make a same mistake she made when she married my Dad. 

I ignored her first email because how she act toward me in the email wasn't appropriate. She said a lot of hurtful things and I didn't appreciated it and I want a time to think about what I was going to say so I wouldn't regret it later.

She emailed me second time and was really harsh about it. The thing about my fiance is that he is a FTM transgender. My parents knew this for a long time and they seemed to like him, but in the email my mother was like, "I know he was (his old birth name). RUN AWAY."

Clearly, I was upset and continue to ignore her email. She sent me another email threating me about how she need to draw up legal documents for me to sign. I was not comfortable with this and how she behave toward me was hurtful enough. We never have a good relationship growing up.

My Dad on the other hand doesn't support the idea and expressed same concerns but in much more rational way. He was divorced twice.

We are happy together and very much in love, but I have come to notice that when I mentioned that I'm engaged. I feel a sting in my heart because my parents doesn't support the engagment and it's supposed to be a happiest time in my life.

I haven't spoke to my parents in nearly a week. Just because their marriage doesn't work out doesn't mean our marriage wouldn't work out. I know they have my best interests at heart but it really hurt. This is the happiest and healthiest relationshop I've ever been in.

Advices would be greatly appreciated.
