What can I do about my housemates boyfriend staying over?

Everything ultimately changes and not being a cosy twosome isn't anyone's fault. You aren't going to break them up and you shouldn't interfere with her life. However, she IS interfering with yours. They are just a loving couple and they aren't deliberately rubbing your nose in it. It just feels like it because you appear to be a bit sensitive that you don't have a boyfriend while she does. Perfectly natural of you.....but a bit unreasonable. What IS really unreasonable though is them pinching all the milk and using up all the washing powder. As to them keeping you awake at night you are just going to have to get earplugs. What she does in her own room isn't your business. Show her the earplugs when you buy them and mention jokingly that the walls are thin and you feel like a voyeur. She may not realise that their every whisper is overheard and she may tone it down if she's suddenly embarrassingly made aware of a third person listening in the next room. You don't want to fall out with her but I think you need to change a few house rules - with her agreement of course. (He doesn't come into it where house rules are concerned). You only put up with them 4 days a week so ask your friend to bring in an extra pint of milk if he's staying over because 'we always seem to run out nowadays' - and while she's at it, maybe the odd extra packet of w/powder to cover his laundry would help too. Emphasise how much you enjoy living with her and tell her you miss those cosy girly chats every now and then. Boyfriends usually come and go and you'll be the sympathetic shoulder when this guy moves on. Remember, she'll have to put up with you and your b/f one day and will no doubt feel the same when she's alone and you are all loved up. Be truthful, but diplomatic.

Are you definite he's one of these nuisance? Probably he feels as awkward as you do. If you have not already, you will have to try reaching out to him. See if possibly he's a enjoyable man to hang round with (heck, your roommate need to see whatever in him.) If he really is a huge predicament, the first-class way to address the challenge would be to immediately speak to your roommate about it. Do not attack, just maybe advocate she stay with him for weeks as a substitute. Let her comprehend you believe uncomfortable with anybody who's truly a stranger to you. Let her be aware of you're inclined to get to grasp him, however that you do not need an extra housemate who is just not necessarily essentially the most well mannered.

you don't do anything! i'm sure you're still going to be really good friends she just wants to spend time with her boyfriend, don't make her feel bad thats not nice... they're not rubbing it in your face either, you just take it like that because you are JEALOUS!! jealousy is a *****. and just tell them about the milk im sure they will be fine with it. just speak to her like normal (how friends speak) and deal with it nicely :) I'm sure you'll find a girl/boy friend and everything will be fine then, put for now just be nice to her she probably is upset that you are upset with her for being with him.
