What is irritating me right now.......

I don't really get irritated that easy, but there is one thing that has been increasingly irritating each day. I have a wonderful roommate. I have absolutely no complaints about her. She is also a really good friend of mine. She started dating this guy a couple months ago and since then he has been around night and day. I love her boyfriend, he is a great guy. However, three is a crowd in an apartment. I understand that they want to be together, but does he have to be here, literally 24/7. He is even here when she is not sometimes, and that's just super weird. Many times when they are here, they are not even in the same room. She will be studying for hours in her room with the door closed, while he is in the living room watching TV. I don't have a lot of time to relax and just lay on the couch and watch TV. When I finally get time to do this, her boyfriend is always on the couch watching one of the many shows he has recorded on our DVR. I feel awkward making him stop his shows, so I just go back in my room. He even showers and does laundry at our place. The worst part is he washes like one thing at a time and that really drives me nuts. He even bought his own food to keep at our place. It is already crowded with me and my roommate's food. I just can not understand why he does not do this stuff at his house. He has a really nice place with his own bedroom and bathroom. He has his own key and sometimes he just shows up and lets himself in. One of these times happened to be when I was sitting on the couch in just a t-shirt and my underwear......talk about awkward. They never hang out at his place. I want to say something, but I don't want to make things weird between my roommate and I. That just makes the situation that much more irritating!
