I'm quite young, 21, and have been in a relationship for more than 3 years with someone who I love and who works very well for me. Right now, we are students and live with his brother to cut costs.
Soon we will be graduating. I already have a great job lined up, and kind of want to move on to working and living my life in the city. I'm excited to find a place in my neighborhood of choice and settle in. My boyfriend is also excited about this.
It's his brother that I'm not excited about.
Lately his brother has become distant, obsessing over his schoolwork and various projects. We see him very little, and when we do its for a few minutes before and after he does projects. He has pushed away friends and family to the point that they don't even bother anymore. We pay for his food, which he eats eagerly, and he is starting to talk about not having money to pay rent. While he doesn't come out of his room often, his presence in the house hurts my boyfriend and my sex life. My boyfriend does not want his brother hearing us, the walls are thin, and we are so nerve racked to stay quiet that we don't bother at all while he is home in the evenings.
My boyfriend is extremely loyal to his brother, and I don't want to hurt either or pull them apart. It's one of those strong bonds that I do not want to trample on, as the girlfriend.
In any case, I don't want his brother to keep me from living my chosen path or have him hurt our relationship. I would be happy if his brother were to find a living arrangment at his school, so we would be close enough to visit often and try to keep up a relationship, but not share a small, city apartment.
How should I go about this situation? What can I say or do without overstepping my bounds?
