For context I (27m) live with my girlfriend (28f) in an apartment with 2 bedrooms, we share one and the other is for guests, we both have stable jobs and are just about getting by.

I don’t have a very good relationship with my family its personal so i wont get into details but me and my sister who is 21 aren’t that close but still look out for each other. One day I come back from work and she’s sitting on my sofa talking to my girlfriend. To summarise her drug dealer abusive ex boyfriend got her pregnant and then bailed on her, she tried to deal with it by herself for a few months but money became an issue for her. she went to stay with our parents for a bit but said they were trying go convince her to abort it so she left, i’m all she has left.

Of course i let her live with us, me and my gf helped her out and she volunteered to do the housework while we were both at work. It was great finally having a sister again, but after a month I noticed that she had not been doing most of the housework which i initially ignored as she is pregnant but then i rarely started seeing her around the apartment. She seemed to be always in her room or out with friends, one day when she was out with her friends I went to go look in her room to maybe find out why she was never in, my gf disagreed but something wasn’t right to me. To my horror i discovered she had been using this room to take drugs in, on the desk was remnants of white powder and empty small bags (i had never been in her room before because she asked me and my gf not to because she wanted privacy). My gf came in and was as shocked as I was, she said we cant have her living here to do that as she was also harming her unborn child in the process.

When she got back at 1am, we confronted her to which she started breaking down and asking to stay. I told her she cant be doing this as it’s dangerous for her child and that she’s blowing money that she doesn’t have. I told her to pack her things and that i want her gone in the morning. I went to bed feeling guilty and wondering if it was the right thing to do, my gf kept saying it was. When we woke up she was gone and i think she blocked my number. AITA?
