This decision can have such long term ramifications. I don’t mean to sound harsh but this is going to affect me now and I am stunned she did this without even consulting me. She knows how strong I feel about this and we could have talked about this together.
I know why she got the vaccine and I know her hands were tied. She didn’t want to get it and I would have held her hand and went through all lawsuits possible to get justice.
I might not be able to have kids with her.
Hey friend. I'm sorry this happened and I have experience this same thing with my son.
That said, do not take the advice of these commenters telling you to end your engagement. Your fiancé is the one who will be there for you when you need it, not the people on this forum.
Have a conversation with her about how it made you feel. Make sure you're aligned on your approach to vaccinating your children. Strive to gain her trust and for her to gain yours.
But do not call off your wedding because of this website.
