Is OTHER wrong in the post ? POST : Hey guys,

I apologize in advance for the wall of text but I'm quite lost and hurt at the moment.

My boyfriend \[28\] and I \[27\] have been dating for 1.5 years and for the most part he has been a kind and supportive boyfriend, although he hasn't taken much of an interest in my ongoing rare health condition. Without going into too much detail, I have a very rare condition that started 5 years ago and has been getting increasingly worse the past 2 years. I'm in a lot of pain and on bad days its quite debilitating and affects my quality of life greatly. In addition if untreated it can result in potentially life threatening issues (blood clots leading to stroke, heart attack etc.) My boyfriend has watched me suffer with this condition through our relationship and go from doctor to doctor looking for help, without much success (due to my disease being very rare). 

&amp;#x200B;

I finally got an appointment at a renowned research hospital that specializes in this disease. I would have to be there for 3-4 days and it involves a 4 hour flight from our home city. The hospital recommends someone accompaniy me since  I would have to cease taking my medication for multiple days before the flight/appointment and will be in need of assistance due to increased physical symptoms.

I don't really  have anyone else to go with meme. I don't have many friends in the area, my father isn't really in the picture and my mother will not be able to to get time off work to go with me, so it only leaves my boyfriend. He initially offered to go since he's in tech and can work remotely, and he has flight credits to use for the flight there.

However, now his roommate announced he's moving out at the end of April and my bf will need to find a new roommate.

He says he will be too stressed with finding a roommate and can't leave in April for multiple days (my appointment is April 16th). He asked me to move the appointment and I told him I will have to go back on a 6-12 month waitlist if I cancel, but he insisted having a good roommate is important to him and April will be busy with interviewing roommates. He seems to very concerned he will have to pay rent on his own for a month if he doesn't find someone. However, we live in a large tech heavy city with people always looking for rooms and he has a decent apartment.

&amp;#x200B;

AITA for thinking he's being incredibly selfish considering how much of an impact this disease has on my life?

Thank you for everyone's advice!
