Wtf is wrong with my family.

So Christmas is in a few days right. I no longer live with my mother she literally haggled to move out of her house whenever she doesn’t get her way I need to leave her house if I trying to do my schoolwork and she calls me and I say I’m doing schoolwork give me a second she tells me I need to leave her house ( I know what some of y’all are going to say I should’ve left your mamas house a long time ago and I don’t care.) The point of this post is I now live on my own I pay my own bills with the help of my fiancé we are paying our rent which is like 2000 something a month including all the bills that we have to pay and then we are saving money for a wedding that got pushed back by a year. The hours at my fiancé‘s job got cut my hours weren’t great before but they also got reduced. And my family knows this, now my sister comes to me she wants to buy a Christmas present for my mom but it needs to be $65 each person I get it she’s my mom and I’m telling them I don’t have it and this is their thing that they’ve been doing ever since I moved out of the house is because I now live on my own I have money whenever they want money I should be able to give them money because I now live with my man so therefore I have money my man pays all the bills I don’t do anything with my money so I should just have money sitting around I’ve numerous times explain to them that’s not how it works my fiancé isn’t the only person that pays bills in the house I pay bills in the house as well because I wanted to pay bills in the house my identity and my relationship with my fiancé isn’t a financial relationship I’m not going to sit down and depend on him to pay every single bill in my house that’s what you want for me but that’s not what I want for myself she’s going on vacation and wants me to spend money to take care of the things that she needs when while she’s getting ready to go on vacation she’s going on vacation ends when I got a job she’s telling me since I have a job now I should give her money to go get her hair done to go on vacation and I told her I don’t have money she got mad at me I didn’t speak to me for the whole entire time we just take the whole month and a couple days she went on vacation she just spoke to my sister not me then when she comes back from vacation she had the audacity to look at me and tell me she wants a new car and me and my sister that also don’t understand I don’t have any fucking money because I pay bills on my own should give her $100 every week to contribute to her buying a new car when there is absolutely nothing wrong with her fucking car (I don’t even have a car anymore). And if that wasn’t fucking fantastic she then comes that she wants to go on another vacation and that we should pay for the vacation that she wants to go on and then if that wasn’t also great since I can’t do any of those she wants a Gucci bag and I should pay for the Gucci bag I don’t have any money and it’s like I’m talking to myself every time I tell her I don’t have any money you live with your fiancé, so!. I even show them my bank account I don’t even have a bank account Cuz my bank closed my account because I don’t get a monthly deposit in there and then on top of everything she wants us me and my fiancé and everybody else to go on a family vacation next year. I have literally right now $169 to my name and $165 Has to be paid to the phone $1692 have to be paid to my college not to mention we have other bills coming up this month that we haven’t paid yet but she’s mad at me because I’d rather pay my phone bill then give her the $65. What I would like to know right now is would it be wrong of me to just block their phone number and not answer them whenever they text me or call me?
