Do I have a right to feel annoyed ? * LONG *

So basically this girl she’s 18 is / was with my daughters uncle *not real uncle* he’s her nino & my fiancé’s friend. Okay anyways we get along an everything but it just seems like this girl has a lot of problems I feel bad for her. So one day *friday* he breaks up with her calls her mom to come get her etc.. she then calls an wakes me up crying hysterically saying he’s sending her back to her moms & that she can’t go back because of family issues and whatever. So me an my fiancé just got our own place together for the first time I’m currently pregnant with our second an due any day now we haven’t even moved fully in or even have things ready for this new baby we are trying to get everything together so she asks to stay a couple days I felt really bad because if her situation is as bad as she says then I would feel wrong sending her there so i said okay after talking about it with my fiancé so im trying to help her get a job , an get government assistance so her an her mom can get a place now here’s the part that frustrates me to the fullest. She says her mom wouldn’t be able to drive her to work an that she doesn’t know who would take her an etc .. I then explained rn they have a carpool option and also her “ex” said that he would still help her out when she needs it so I told her if he really wants to help he can drive you to work PLUS there is a bunch of other places hiring over here also I’m trying to get her to be independent so that she doesn’t have to rely on anyone if they keep letting her down like that. But every time I tell her to call places she makes excuses, an she makes excuses for her mom as well like saying “oh she’s not replying “or “ya she replied but I forgot to ask her “ I pretty much have done more than enough for her to get started I gave her numbers an websites I gave her hiring jobs that need people immediately I’ve called a bunch of people that can help her out my friend said she can get her hired at her job because they need 3 people like I’ve done more than she has so far .. an everytime I ask if she called or anything she has an excuse. Alright ALSO her ex has been picking her up and texting her and they just went out tonight she cries so much about him cheating and treating her soooo bad an that she needs to move on but I’m trying to get her to get her shit together an all she cares about is him. Now don’t get me wrong if you wanna be the guy then do it I don’t care that’s your life but I am tired from being 9 months pregnant, moving into a new place ,an getting ready mentally and physically for a new born on top of having a toddler I feel like I have so much going on that I don’t need another person to take care of an me an my fiance have lived with SO many people now that we have our place I thought we were gonna finally have that peace. I’ve tried talking to her about going back to her mom an she just refuses also she isn’t really even aloud to be here because our landlord said for an extra person it would $300 more on the rent we already pay $1300 we can’t afford $1600 for rent. I know I’m the one who invited her in but I sat her down the first day an told her she needs to get her shit together for herself an make money and be independent if she can’t rely on her own family. So that isn’t happening I guess an I feel stuck I don’t even know if I’m aloud to be upset an right now she text me saying she was back if I can open the door then she asks if it was alright that her “ex” spends the night. It honestly made me so upset I need this girl to leave her mom pawns her off on anyone that will take her An she isn’t my responsibility I wanted to help her out ofc but I don’t wanna be taking care of her an also if he’s gonna be picking her up an acting like they are together still then he can take her back to his house an let her live there again. She just sits on the couch on her phone all day anyways ugh what do I even do or say I don’t wanna be mean because I realize she probably has went thru a lot with her family but I can’t have her here anymore I don’t need the drama with her an her relationship an her family I have a lot going on at the moment I don’t need anything else to worry about. How can I tell her she needs to go without sounding like I’m just throwing her to the dogs pretty much? An I have been very honest with her from the beginning I did tell her that I’m pregnant an don’t need this drama rn I’ve told her how I felt very plain and straight to the point but all she says is “I know “and “ okay “an “ I get it “
