Some-timing "friends"

Kia
Okay so this may be long just heads up. And sorry if I posted in wrong room, this was the closest option. 
I have...had, a friend who I've been friends with all through HS and here 4 years after graduating. She's gay(well technically bi but she doesn't really talk to men). Well last year sometime her mom found out she was gay (long story short I beat up her cheating gf who literally left her heartbroken and afterwards the girl and her mom showed up and my friends house to tell my friends mom she way gay for whatever reason) Anyways, after my friends mom finds out she's gay she kicks her out and my friend has nowhere to go so she came to stay with me and my SO. Well she was really only supposed to stay a couple weeks till she could come out of her feelings and get back to work and normal routines. She has family and friends but we were close at the time and I wanted to make sure she had somewhere to lay her head. 
She again, was only suppose to stay a couple weeks a month at most. Month(S) are going by and she still hasn't left. She's been coming with me and my SO literally everywhere, movies, restaurants, my family gatherings, church, his family gatherings, etc. people began to ask wtf was going on lol. We got questioned a lot about why she always needed to tag along "does she think y'all are a threesome?!" Stuff like that lol. Never really bothered us cus she was like a sister and still kinda heartbroken at this point. 3 months in, she offered that if she was gonna stay longer she was gonna give us 100$ a month for food, water, lights etc just bc she's kinda living off of us at this point. So we obliged and accepted the offer. 
Skip 7 months later, she's STILL living with us. Hasn't attempted to go anywhere. She's still working and has not paid us 1cent even though she's the one who offered. I became pregnant last May even though I didn't find out till July due to irregular periods. Me and my SO started going out on our own, having little dates, because we felt at this point she should be so used to living there it shouldn't even bother her if we wanna spend time alone. She started getting extremely jealous anytime we would go out and it showed. We would come back and she'd have a whole bitch ass attitude because we didn't invite her! 😒 so one weekend since she was ALWAYS at our house and didn't wanna leave, we got a hotel for a day and came back the next day and she and all her belongings were gone. She sent me a long text later that day saying we needed to talk in person. Basically we met up and she called herself letting me have it because we made her feel uncomfortable and unwelcome??? When I asked for reasoning behind how she felt she said because we started to leave her by herself and not invite her with us. I explained to her that this is a 2 person relationship and sometimes we wanna do stuff alone and have our time together. I was never in any way rude about it. She said she was mad bc we knew what she was going through with her ex gf and that she was still heartbroken and we shouldn't have made her feel like that?? So I'm really baffled at this point. After this long convo she broke our friendship off. I'm not 41 weeks pregnant and last month contacted me the day before her birthday saying how she has a new gf and how happy they are. I told her happy bday and we shared a few texts. She never once asked how the baby was or how anything was going. I feel like she only contacted me to gloat about having a new gf in a way trying to make us jealous? (Because I know how she is). But I really feel like it was selfish of her to even text me on HER birthday (after mine and my SO bday has passed) and only talk about herself and new gf as if that was supposed to make me jealous for whatever reason. Mind you, she still technically owes us for the 8 months she stayed with us and knows it's around time for my baby to be due and didn't even bother to ask how we all were doing. I wanna text/call her and tell her about herself and get my damn money lol but I feel at this point it's not even worth it! Sorry for the rant. What would you do in this situation though? Am I wrong for feeling how I feel towards her or would you feel the same way she did? I've tried to see myself in her position but I just can't because I've never been one to rely on anyone but myself.
