My XH dragged the divorce out. Refused to sign the decree for months. Then all the sudden wanted it done like tomorrow. I later found out the OW was pregnant.
The OW in my situation is a nut job. She doesn't act like most normal people. So I wouldn't even want to compare her to someone else or what someone else might do.
She doesn't even like kids, can't stand them but has 3 of her own. Of course she only physically has 1 of those kids.
I don't think you are wrong to feel that way. Actually I think it's normal. You have a lot to process. Did you find all this out in one day?
