About fed up!!!

So I let a friend of mine stay at my apartment with the agreement she'd pay 200 a month (50 a week) to stay here. I pay nearly 1200 a month to stay here plus all the bills. Also I put food in my house and let her eat it as well. Well things were fine at first. But she has recently quit both of her jobs. So now she hasn't paid me in two weeks. Mind you it's Christmas time and I have no money for gifts for my family because I'm struggling helping her out. I'm also 16 weeks pregnant. She found out last week she is pregnant by her mentally ill and abusive boyfriend whom isn't allowed at my house anymore. I told her that she needs to pay me the 150 she owes or be out by Friday and literally I have seen no progress by her to even try to come up with the money, other than asking her family for it. Also her boyfriend and her argue damn near daily and they both blow up my phone when they have issues. It's causing me to much stress and plus she goes back and forth with wanting to keep her baby or get an abortion. Every time her and her boyfriend fight she says something like "this is why I'm aborting my baby". I'm all for pro choice but don't flaunt your abortion especially going back and forth saying your keeping it one day then shit gets rough and your gonna abort. I want her out by Friday. I don't even want the 150 anymore. I just want her out.
