In laws 🙃

So my fiancé’s parents suck. Like they recently “disowned” him over something political he posted on Facebook (they haven’t spoken in about a month) and when he was in college they “disowned” him and didn’t speak to him for weeks when they found out he’s bisexual. I minded my own business until my last pregnancy ended at 9w in March and they accused me of having an abortion (nothing against abortions but I didn’t have one). It was the most traumatic thing that’s ever happened to me and I’m still recovering physically and emotionally from the pain I went through so for them to accuse me of that with absolutely no information or proof just really hurt me. Anyways I’m 5w pregnant and I just know they’re going to try to sneak back into our lives once they find out. I guess my question is- am I in the wrong for not wanting to see them? My fiancé doesn’t want to right now either but I figure he will eventually forgive them and I don’t want to keep him from them but I also don’t want to see them (they’ve never once apologized to me or my fiancé). What would you do?
