How do I get my girlfriend and her mother off my couch?

I'm 26(m) and I have a 30(f) gf. Her mom is in her 50s. She has short red hair and a black nose ring. <br><br>A few months ago my gf's mom lost her house. She was evicted, her sister died, her dog ate her homework — doesn't matter why. I was only too happy to help out so I said she can stay with me. <br><br>I have a 3 bedroom house — my parents died in a car crash when I was 17. My only sibling is an older brother, who is a monk in Tibet. So I inherited my parents' house. <br><br>My mom and dad were good — I don't mean to bad mouth them. They left me this beautiful 3 bedroom house and I'm very grateful. I don't know what I would do — or where I would live — if my parents hadn't left me this house. It's very difficult to buy a house, my parents told me, so saving for one is very important. <br><br>I put my gf's mom in the extra bedroom I have. Then about a week later my gf — Rachel — moved in. She was very proud of me for letting her mom stay and — well, you know — it was great. <br><br>So things went for a while — maybe a few months. About a month ago Rachel's mom lost her job. I was sorry when I found out, but it didn't really matter because she was already staying at my house. <br><br>Then, Rachel lost her job. She was very upset and worried — she is a very caring woman — but she didn't need to worry. I have a very good job — I'm an engineer — and I make plenty of money to pay for the house. So even though she lost her job Rachel and her mom can still stay. <br><br>Last week when I came home from work Rachel and her mother were in my bedroom. They were naked — they were skinny dipping in my indoor hot tub. <br><br>I was a little annoyed — it's my hot tub, after all — but I was happy when they invited me to join them. So I took off my clothes and got in the water. <br><br>We had a good time, drinking and talking. Then I — well, you know — it was very fun. <br><br>Then, when we were done, I noticed the sheets on my bed were missing. Rachel — my gf — said they were in the washing machine. I was a bit annoyed but I figured it didn't matter very much. <br><br>Then, I went to take a shower and the towels were missing. I went back to my bedroom — where Rachel and her mom were still naked in the hot tub — and I politely reminded them that I don't like it when they take my things — sheets, towels, etc. <br><br>They said it didn't matter because it's "just stuff" but I think it matters a lot. My parents bought me those towels and I'm very attached to them. <br><br>So, I suggested that Rachel and her mom help me pay the bills. They can pay to replace the towels they stole from me, and they can pay to contribute to the house. I'm getting tired of paying all the bills myself. <br><br>They said no and started yelling. They were very nasty and called me mean names. Then Rachel — my gf — told me she will — well, you know — it was very nasty. <br><br>I was sad — I didn't want to say those things, it didn't make me happy. But I didn't see any other option. <br><br>So I asked Rachel to move out right away. Then I politely asked her mother if she would also move out, but she said no. <br><br>She told me she is not — well, you know — it was very insulting. She said she can stay "as long as she wants" and that she will "kick me out" if I try to make her move. <br><br>So I thought about that — I can see — well, you know — it doesn't matter. <br><br>I can see why her mom doesn't like me. Rachel told her very bad things about me and — well, you know — it doesn't matter. <br><br>I can see why her mom thinks she can make me move out. I told Rachel she can't live here anymore. Now she's with her mom, and she's being mean to me. <br><br>I don't know what to say to her — I can see I made them upset. I was trying to be fair but I hurt their feelings. <br><br>Can anyone help me?
