Boyfriend isn't comforting me after friend died

On Tuesday, I lost a childhood friend to suicide, the second friend I've lost to suicide in the past 8 months. I'm away at college so I don't have any of my home family or friends around, I just have my school friends and my boyfriend. My boyfriend happens to have midterms this week. I've been trying to keep it together as best as I can but it's really hard and I just get hit with waves where I break down. I was hoping my boyfriend would come see me (we don't go to the same school, ours are 30 min away) but he's only texted me and called me for 5 minutes when I really need him. It's hurting me even more not to have him around. We've been together for 2 years. Is this normal? I'm already feeling so upset and to add to it the feeling like he doesn't care enough to come see me, when if one of his friends ever passed I'd drop everything and go see him. I know school is important and I don't want him to get bad grades because of me but I don't know what to do.
