You are in a hard position.. He needs somewhere to live, and he's made a commitment to his friends that he would move in with them...

The reality of live is we're not always going to get on with everyone our partner hangs out with.
Unless you have some rational, defined reason why this woman is a danger to you I don't think there is anything you can do.

Maybe be the bigger person and make an effort to mend the bridge with this girl and give her a chance to get in your good books?

I may be a little harsh but for almost 18 years of my life I've dealt with trying to express "I feel uncomfortable" In everyway. There are many factors I understand and many many other places to live. So he bails out on his boys or he finds another you? Just my opinion. Do remember it took me 18 years to stand firm, don't let it take you that long...I'm 34 also...Good Luck<3 Katie

If you're living far away anyways you probably won't be going to sped a lot of time with that girl...
And what your boyfriend said about that being okay because that girl has a boyfriend probably means that he thinks your jealous and wants to ensure you that she isn't going to hit on him :)
So I think you should trust your boyfriend to become not more than friends with that girl (which you probably do) and when you meet, try to do something that won't involve having her around... :)

Ahh...Yes, I know this feeling well. My boyfriend and I are in a long distance relationship (1500 miles apart) I pretty much hate every girl I hear on his end of the phone. The motto I live by that helps me out: Trust him until he gives you a reason not too.

He's moving in and there's a girl there. Okay. She knows that you are his girlfriend ad she obviously has a girlfriend. I know how it feels to sit around and wonder what's goin on - to not be able to "defend your territory" So, ask yourself these questions:
Does he love you?
Do you trust him?
Would he ever do anything to hurt you?
If you answered: Yes, Yes, No. Then just trust him until he gives you a reason not to. EVEN IF things sound fishy...don't jump to conclusions. Ask him about it - be totally honest and up front. Just call him and say that something's been bugging you but you don't wanna accuse you just wanna talk about it to make sure you're not jumping to conclusions.

^^Doin just that is what has gotten Steven (my bf) through really tough times. One of his best friends started hitting on me - I would just answer politely because I knew this was Steven's friend and I didn't want to go at Steven saying that his friend was hitting on me. Soo..I just let things be - until another friend caught him in the act and Steven found out, he didn't jump to conclusions that I was flirting back - he just asked me what we were talking about and I told him the truth. He got a hold of his friend's phone and saw the proof and found that his friend was hitting on me, and I replied just as I had said. our trust grew so much stronger at that very moment. So if you ever hear of her hitting on him - don't instantly get mad. Ask him if it's true, ask him how he's dealt with it - and by the way he answers - you'll know what to do! =)

Trust is the key! Trust him until he gives you a reason not to! Good luck with it all and I'm so sorry you're in this postition - it's a pretty tough place to be. But think about when it's all over and he's moved out and in with you - won't it be worth it??? =D Have a good day!

ask him to change roommates or something.it's not like it's a bad thing to ask for another roommate and besides if he really loves you he should understand the fact that you and his supposed roommate don't get along.what's the big deal?you don't like her he should know that.and he should be willing to change roommates if they don't have something going on between them.i'm not saying that there is but you'll never know.so what if the girl has a boyfriend?maybe she's a two timer.again.we'll never know.so try to ask him to change roommates and his roommate should also be a guy.

If he cares about you that much, he'd respect your feelings.
It's perfectly understandable that a situation where he's living with another girl would make you uncomfortable. It would drive me nuts. It doesn't mean you're selfish or jealous or unfair, it just means that you're human. And so is he. People make mistakes, and it's understandable that you might be concerned that he might make one, what with having a girl so close by all the time.
Be strong.

My boyfriend and I are in a long distance Relationship and when I say long distance I mean it. Heh. He's in Canada I'm in Florida. Long ways away. So I know how it feels to stress over your boy being around another girl. If my boyfriend was doing something like that, I would suck it up and trust him. If you truly love your boyfriend, sometimes that is all you can do. Trust that he loves you enough to know not to cross certain lines. It is hard (Believe me I don't trust easily.) but it is worth it because no matter the outcome, you find out exactly who the man you are with is.

if i was in your position i wouldnt just be explaining how uncomfortable it makes me feel.. tell him that you trust him but its weird.. ask him what he would do in your position ask how he would feel if you were going to share a room with another man. if he cared about you he would listen to you and see that its hurting you but he isnt so make him listen its the only way he's going to see that its not right..
