I don't want my step-mother at my wedding?

I am 18 and I am getting married on July 21st on the Canary Islands to my fiance Adrian, we have been together since we were 14 and 15 and have known each other since we were kids. My mum died when I was 9 and dad remarried. I have invited him to the wedding and their son and daughter but not his wife. I have told him she is not welcome and we will not pay for her to come.
Dad said she has a right to be there and I told him she has no right. The reason I don't want her there,
1. We have never gotten on and hate each other,
2. At my graduation (I graduated high school at 16) she insulted my mum by calling her names and told my soon to be mother in law that only stupid people would hang out with my mum who was a b**** and a whore she said all this in front of everyone,
3. She will do it again I know she will.
I hate her which is reason enough for me not to invite her. Lucy my mother in law told me that she will not be able to come if my dads wife is there. She loved my mum too and when she insulted her at my graduation I slapped my dads wife in the face. Dad still says she should be invited but its too risky. Its only going to be a small wedding with the people Adrian and I love. What do you think?

Hi,

First of all you have to ask the question Will you get married without your Dad? if the answer is

yes then you need to tell you dad that the ball is in his court either he comes alone or not at all.

If the answer is no and your dad is unwilling to go without her then you will have to allow her to come but put plenty of conditions in place, like she must stay away from your future mother in law etc.

So at the end of the day it all depends on how desperatly you want your dad there (which i know

every girl wants their daddy at their wedding) 

hope that helps :)
