<human>: Condense the text into a few key points

In December of last year I asked my girlfriend and her young daughters to move into my house with me. Everything seemed to be going well until about 4 months ago my girlfriend started sleeping on the couch. I have asked her why she doesn't want to come to bed with me and she says its because she has trouble sleeping. 

Just over two months ago she lost her job because she was taking too many unnecessary sick days. Since then she has deteriorated into worsening depression. She doesn't help around the house. She doesn't help with meal preparation. She drinks nightly, has started smoking cigarettes again and watches Netflix all day while I'm at work. I have told her this isn't okay.

I am feeling like I am trapped. I feel like I am the only one still invested in this relationship. I don't feel like I can ask her to move out because she doesn't have a leg to stand on right now and I would essentially be putting her and her two young daughters on the street. I'm not happy. She certainly isn't happy. I don't know what to do.
