My Girlfriend's Sister is Homeless. It makes me happy.

We gave her a place to stay 8 months ago because she didnt read her lease terms, and she had to move out before her new apartment’s move in date. We were very hesitant, but convinced my girlfriend to help her family out. (We are 23 shes 25) When she arrived she had no respect for our house and our rules, and when addressed, she proceeded to slam the door in my girlfriend’s face and loudly talk shit about her in her OWN office. The amount of disrespect is absolutely appalling. Back then my girlfriend refused to allow me to intervene because im too much of a “hot head” and “hood”. So i sat and watched this girl turn our house upside down. Her boyfriend even entered our home without permission and locked me out (they arrived when i was taking out the trash). It all ended with her being kicked out. We told her a time to get her things and she wasn’t there so I put her disgusting shit right outside our door and texted her to come and get it at any time. This pissed her off, and so she accused me of besting my girlfriend to their family, and stalking her. She painted me as this dangerous individual and it took showing my entire facebook transcripts to prove that she lied. Even then the relationship with her family was never the same. I am not too comfortable with them. I used to play video games at their house, visit all the time, have deep talks with dad, but that all stopped. She caused an ungodly amount of stress to my woman. She grew so much from the incident though. Color me shocked when we got a call asking if she could stay for 2 weeks because her new apartment evicted her ass. Shes staying with her boyfriend (he lives with his parents), but her things have nowhere to go, but this time me and my girlfriend wont be there to help her, shes truly on her own. In addition, their parents moved states away and they’re phone is off currently and they cant be contacted by anyone. She doesn’t even have them to help her. Oldest sister, who is a saint and lectured us about being cruel suddenly has no space for her. The universe really did make her pay this time. I didn’t believe in karma before, but boy, this is hitting her hard. We were told we were causing a rift in the family for kicking her out, but now we are focusing on ourselves. We cant be blamed anymore, and im proud of how strong my girlfriend has become. She would have never been able to say no a year ago.
