Is she helping or winding me up?

It's by no means definate yet and I don't want to count my chickens before they've hatched etc, but there is a possibilty we may be moving in a couple of months time from our 2 bedroom flat to a 3 bedroom house 😀
Anyway, I am very very good friends with my neighbour, we are like family, and it will be abit sad to not see her every day out the window or for a cuppa etc but we need a bigger place! She has expressed that she will miss us, although the house we might be moving to is only in the next road over so really we'll still be very close. I've said that it will be strange for me too not living under her any more etc etc, but we will totally see eachother lots still. Anyway, since we've told her about the house I'm not sure if she's trying to be helpful, or if she's trying to put me off moving because she's said so many things about the next door neighbours where we'll be going. All bad things to suggest that we shouldn't move there, but the thing is that her daughter is best friends with the girl of the family who would be our new neighbours so if they were that bad would she really let her daughter be friends with this girl and go to her house? Also, most of what she's said could be general stuff which is blown out of proportion and may not really affect us as their neighbours anyway. She has also been fussing about who she will end up with as her new neighbour in our place if we leave; and not being mean but really that can't be my concern. I feel abit miffed with her because in my delicate emotional pregnant state she has put doubts in my head, when in actual fact the house, the area, the move is exactly what we want/need. I don't know if she's being selfish saying these things to me or if I'm being sensitive and worrying now over what she's said 🤔 I mean we could go anywhere and end up with bad neighbours without knowing beforehand, and as I've said the problems she has told me about with these people may not even be noticable to us next door. I don't know if she's saying this to try and get me to put off moving until further down the line for her own reasons, because I can remember when there was a chance of us moving about 2 years ago she was saying how the area was quite rough and how she wouldn't want to live there. Then we didn't move anyway! But on the other hand I don't want to move to this new place and be stuck with awful neighbours who make life miserable if the bad things she is saying will affect us, because this move would be a permanent one probably for atleast the next 20 years if not more which is a seriously long time. What do you all think?

I don't know to be honest. Maybe you are such good neighbours that she's worried who she'll end up with instead of you?
