Hi guys. I haven't been on DNN for ages...like perhaps just over a year. So hello again!

I've been living with this girl, Sam, for almost a year now. Over that time we;ve become really good friends.

She recently met this guy, Blake, at a bar. After their first date, she brought him home for coffee. I spoke to him for about half an hour and all he spoke about was himself. He went on about his 4 houses, 3 cars and a harley bike. I was trying to be nice and said he had a nice watch. He then told me how much it costs (almost 2 grand apparently). He asked me what I did and I told I play the violin and piano at the con and he says he too plays both brilliantly and has perfect pitch. I seriously doubt he does, but he's just the most arrogant prick.

When Sam went to the loo, he leaned close to me and said (exact words), "Just between you and me, Sam is the most superficial b**ch I've ever met."

And Sam has this really cool, trendy blond hair that's cut really short at the back and longer at the front.

He went on to say, "And her hair makes her looks like a lesbian...she'll just have to grow it out if we start being seem together often."

I do NOT like to guy. He's mean, manipulative (he's already begun treating Sam like shit when they're in public), says such inappropiate things, and is self obsessed. And I've recently found out that he deals drugs.

Sam's room is above mine. I can hear everything. It's is a very old house, her floorboards squeak and grind as she walks around and the noise is incredible loud. I get startled awake often (she tends to party a lot at times).

He has come over a few times, about 3-4 times. Always in the middle of the night(2:30am, 3:30 am...it's never the same time). And they have sex.

I don't mind people having sex. Really. Have all the sex you want.

She's usually quiet. He's a little loud. I can't stand the rhythmic squeaking of the bed and floorboards though.

I've put up with it for some time. I find to difficult to sleep because I worry he going to come over and ruin my sleep. I'm always on edge when he's over.

But two nights ago...

He came over at 4:30 am. They started having sex immediately after. Very loudly. She sounded like a bloody porn star. 10 minutes in I actually hear her say, "Oh my god, I'm coming!" and then...gasp gasp...moan moan.

He kept up this awful groaning noise. It was so loud! And the rhythmic creaking....shudder...

Then a pause. Some shifting. Then the creaking resumes. This time on the other side of the room....right above me!

I was so pissed. I've been working all day and I needed the sleep so badly.

More of that...and then it changed. There was just him moaning. Louder and louder. But no squeaking. I thought...hm...she's giving him head. And I was right. He finished, swearing and moaning. I heard her bounce off the bed, run down the stairs, and...get ready for this...I heard her spit it out in the bathroom!

Christ. My bedroom is right beside the bathroom!

I very nearly threw up in my mouth.

They had sex for about an hour. It was effing daylight when they finished.

She's usually so considerate. But she really wasn't that night. Neither was he.

I spoke to our neighbor who is Sam's best friend. She was shocked. She told me not to say anything and that Sam will apologize.

She didn't. For two days.

I spoke to her today. I felt so awkward because I hate talking about housematey things.

I kept it short. Told her I could hear everything that happens when he comes over (I've casually said this before). I also spoke briefly about that particular night, and that it was louder and it kept me up and I feel uncomfortable when he's around. (The drug thing really stresses me out but I didn't mention that.)

I have met some of her close friends, all of which have told her not to be involved with this guy. I mentioned it today, saying that perhaps she could take that into account and also that we are just concerned.

She flipped. She says she tries to be quiet and that it's really hard to be in the upstairs room. She says she never lets other's opinions of people get in the way of her own judgements, and that I shouldn't have an issue with him coming over. She said that she doesn't like to him coming over in the middle of the night (yeah right) but she's not going to turn him away because he's a 'friend'. Lastly she said I was rude and was 'talking over her'.

I was a little scared when she began all that. I apologized for being rude and talking over her even though I knew I wasn't. I didn't tell her not to keep sleeping with him, I didn't tell her not to let him come over in the middle of the effing night.

Then she had to leave because a girlfriend was picking her up for something.

Sigh.

I'm hiding out at uni computer lab. I don't want to go home.

Any sort of advice would be great.
