Am i wrong.

Me and my husband let one of our friends move in with us because her and her husband are separating.. it been a year since she moved in with her 3 kids... i turned my basement into a mini apartment for her.. she has everything beside a kitchen and a washer and dyer.. i told her rent is 400 . Is said she ok with that. 3 month into her living with us she tells me that she cant do 400 a month. So i told her250 every two weeks is fine with me.. she says ok.. she starts paying the 250 the first month the 2nd month goes by and she give me 150 and told me that this is all she can afford right now cuz her soon to be ex husband wipe out the account. Ok. Couple days later im outside on my porch doing some school work and 3 different cars pull up in my drive way.. i dont know them.. its 3 really tall buff dark skin men.. i dont say nothing.. then its starts to be a regular thing. I tell her that im uncomfortable with guys that i dont know in my house. She says sorry and thats it.. 3 days later im throwing out trash and i see a crap ton of beer bottles, needles, and a broken razor head. I go down stairs and they whole place is destroyed.. she is sittin on the couch with some dude on her lap. They were watching tv. I tell the guy to leave for i can tAlk to her. Maybe 10 mins into us talking I noticed that she is high. So i asked her how she got money for drugs but not for rent.. she starts laughing. N tell me that she has enough money for rent but she said i was money hungry so she stop paying rent. I told her wtf u mean u have enough money. She then tells me that she gets 700 for 2 of her kids that are disabled.. so basically she gets 1,400 from social security plus600 in food stamps plus 150 per kids from her ex husband.. im livid.. i tell her to pack her shit n leave.. she starts crying and talking about she has no place to go.i told her that she has a month to figure it out.. its now 2 month later.. today i come home and i find her in my bed asleep with some random guy.. at this point in pissed i drag her off be.. she gets mad about me getting mad bout this dude. She then tells me that im only mad cuz she gets more dick than her.. she gets mad takes her kids and leave. She been drinking Nd smoking All day. So while she was gone i packed up all her shit and put it outside by the door. She leaves me a voicemail calling me every name in the book..

i fell bad for her. But i cant deal with her anymore.. am i wrong
