You have every right to enjoy the comfort of your suite...not to mention be there ALONE! You have no privacy! If you had wanted three roommates you would have asked for them.
Look, simply sit down with your roommate and tell him that you don't like it when you come home from a long day and he's not there but his woman is. Tell him that you're not asking him to never bring her by (even if that's how you really feel) but that you would simply enjoy some time to yourself. I mean, COME ON! Do you have to ask her to leave when you want to change clothes? You shouldn't have to...
If they want to spend time together, perhaps they should do so in her room more!
How RUDE!
