AITA for wanting my roommate out?

First I want to start this off by saying that it’s not just a roommate it’s a family member I thought I could trust. Before this family member who we’ll call Alyssa. Alyssa moved out here with me and other roommate who we’ll call Emma. Alyssa stayed in another state and wanted to change her ways so she asked to come live with me and Emma. It was some debating and unfortunately we decided that Alyssa could come stay. We had a 2 bedroom apartment and had to upgrade to a 3 because Alyssa did not want her own apartment she wanted all of us to be together. Alyssa and Emma are both on the lease but Alyssa keeps bringing company over that was known for doing something that were very uncomfortable with. Alyssa told us what they did and expected us to be okay with it. Upon finding out this information we expressed to Alyssa that we know what they did and we do not want them there at all. Well Alyssa feels like because she pays rent they can come and stay when she’s not there. So I decided to tell her and let it be even more known that he is not welcomed there. I told her it’s not that she can’t bring anyone to the house just not him. After this we found out that Alyssa has been talking to other family members about us and it’s been coming back to me. Emma said something as well and even gave her a furniture set that Alyssa agreed to pay but didn’t do. Weeks later Emma had to get her own furniture but still no payment from Alyssa. We got into it really badly and decided we wanted to break the lease. Alyssa texted and told me and Emma that we can find somewhere else and she can stay there. Not happening. I just feel like if you live with other people you should respect what other people have to say. I would never bring someone that my roommates are uncomfortable with. I’m genuinely hurt that this family member would do this after all the crying and wanting to come stay “for a better life”.
