Looking for opinions on my scenario...

So my Mom guessed that I was pregnant back last December and she begged me to tell her if she was right because they were going to move to Florida and buy a new house. But they didn’t want to do that if I was having a baby. I told her yes I was pregnant and they didn’t put an offer on the house.

Fast forward to Summer and I’m out to eat with my family and they tell me they put an offer on that same house and it was accepted. I think - ok this is really strange because not only am I having my first child and we live 20 min from each other but my brother has also not finished high school. Not to mention they kept this a secret from me which seems - sketchy. Then she proceeds to tell me not worry because they would never sell their home here so they would be around plenty over the next few years. They would just have the two homes. I think ok, this isn’t so bad.

Fast forward 1 month and all the sudden their home here in North Carolina is up for sale. And again I find this out over a dinner. They say they want to downsize and they will likely find a townhome to stay in until my brother finishes his senior year. My mom says she also needed to downsize for money reasons because she bought way too expensive of a house.

At this point - I don’t believe the bs story about the townhome because they haven’t even gone to look at them. She also installs a $30k jet ski lift in the Florida home, is completely redoing the pool, and is filling it entirely with new furniture because she thinks her NC furniture is old. Also I find out l from my best friend that my mom just put in an order for a $150k 2020 electric Porsche. So they do not need to move for MONEY reasons. Also they are talking about sending my brother to Clemson which I find hilarious because 1 year at Clemson would have paid for my entire 4 years of college.

There’s more - my little brother “called” the large guest bedroom in Florida (despite him going off to college and not even being there) and if we ever go stay down there (debating for Christmas) my husband, baby, and I will be sharing the smallest room in the house with 2 twin beds. While my brothers large bedroom has a media room attached to it and a queen bed. Plenty of room for the 3 of us and when I asked to switch if we ever came

down my mom said no. I told her common sense would be to put the larger party in the larger room.

I’m really pissed. I’m tired of being lied to. I’m tired of being treated differently than my brother. I’m just so over everything. I don’t understand how a grandparent could move from their kid and grandchild and not blink an eye about it. I could never do that. And as much as I try I can’t understand her perspective.
