Is she pushy just with you, or everyone? My MIL has a big "bowl you over" personality- she assumes her way is the right way, until/unless someone proves her otherwise. BUT, she's this way with everyone. I've learned by watching my husband interact w/ her that you need to be somewaht aggressive back with her- just being firm about your convictions, and not going along with her just to be "nice" (which I tend to do a lot). She might be surprised/offended at first when we don't agree with her plans, but she's over it in like a minute.
If it's just with you, I'd talk to your fiance about it- find out if he can figure out why she's treating you differently than others. She may see it as a power struggle with you- you're taking her boy away! Hubby-to-be will need to learn to support YOU in issues like this, as you are to be his WIFE.
