He and I are both pretty red pill but a lot of people around us are not. His sisters don't have the best relationships with their partner/husband. One of his sisters is even thinking of having children before getting married because..."marriage is expensive..." what? (Also she's a doctor and can afford it). She pushes my bf to do certain things (like she pushed him to make me his gf quickly and suggested I wasn't serious or might be playing around when it had only been 2 months of dating), pushing him to post pictures of us on facebook because she knows I must want that (I'm private, a few times is ok), and now she's talking about us moving in like its natural and he even spoke of it like that. People say things like, "when you guys move in together...etc" but even though I really love the days I spend at his house I know it will prolong the engagement and marriage which I don't want.

How do I deal with this? Especially his sister's expectation that we will move in together? I feel like saying my family is against it or I'm against it might be like an insult to them since they do it.

On the bright side his parents are really traditional so they will probably back me.
