My mom died about 2 years ago. My dad started dating someone casually last September. They see each other weekly, and are either thinking about getting more serious or possibly breaking up in September this year depending on how things go. One sticking point is that my dad's gf doesn't like how he prioritizes his family and she wants to be "number one." So she is giving it until September to see if she wants to deal with that.
Meanwhile, I am getting married in August. I do not want to invite her to the ceremony, but I feel guilty about it and don't know if it is the right thing to do. It will be a small wedding (50ish people) and it is compromised only of people that we know pretty well. I have never met this girlfriend. Despite living one town over and seeing my dad fairly often, I have not been invited to meet this gf or anything. So she is a stranger to me. And to make things worse, she has a "live and let live" attitude towards gays (this is a lesbian wedding) which is not the vibe I want from people attending my wedding.
My dad had told me two weeks ago that his GF doesn't care if she attends or not, so that made it easy to not extend the invite. Now he is saying he wants her to come because she wants to use the event to see how the family dynamics would be with her around.
I am at a loss about what the right thing to do is.
