"Friend" rant.

There's this person I knew for a very long time. She sometimes acted shady with me, but whatever. I overlooked it and we kept going as best friends. Long story short, I got pregnant and she ghosted me basically. She started hanging out with this other girl, big deal right? Well, when that girl was pregnant, she'd go way out of her way to do everything for her. She'd go with her to every appointment and got jealous of the girl's best friend cause the best friend did what she's doing to me now. She always said she couldn't wait for me to be pregnant and once I was, where was she? Nowhere to be found! We went months without really talking or seeing each other cause she's always at that one girl's place. Even her own mom says she thinks it's too much and that she thinks she could get some sort of benefit from that other girl. Why? I got no clue. She even threw her a baby shower when the girl was pregnant. Paid everything out of her own pocket and she once spoke about making me one, but she wanted my husband to pay for everything SHE wanted and it was not cheap, so I never went for it. Yes, I am a little salty about that because here she is claiming to be my best friend and the minute I get pregnant, she was nowhere to be found at all. So I started backing away and stopped telling her things and just made up the excuse that I was asleep all the time and just kept her at arm's length and stopped talking to her slowly. The only times she'd talk to me was when she pretty much needed something or just made small talk. We made small talk over Facebook the other day and today she messaged me saying her mom is "worried about me." She tends to ask where I am whenever my car isn't at home. Why? Nosey I guess? I don't know, but she's always asking. She always wants to know what I'm doing when I'm not here. I don't tell her where I'm at cause I mean, why would I? But she asked the same thing today and said her mom saw my daughter "get into a car" and the car left and my car wasn't here. She's assuming my daughter was home alone and she's being nosey and asking just to see what I'm gonna tell her as to why my car hasn't been here and who my daughter left with and why. I've been home this whole time and there's a reason as to why my car isn't here 🙄 I'm fuming cause she hasn't even bothered to even say hi to me or anything, but now that I'm close to my due date she's gonna try to be there and wants to know everything about everything and at one point she even said "I'm gonna be in the delivery room with you and you can't say anything about it." Uhhh hell no! I don't even know how to reply without being an asshole and telling her to mind her business! It just rubbed me the wrong way that she just wants to know what's up whenever she doesn't see that I'm home or whenever she doesn't know about something.
