Do I have the right to be mad..?

So I've been in the hospital since 5pm with a really bad infection, and my boyfriend and I are long distance so obviously he can't be here. I was really nervous (I hate hospitals) so I texted him, no reply. Whatever, I figured he was busy. Texted him again around 9pm, no reply. Just texted him now and jokingly told him how awful he is at texting and all he said is "I'm with friends". I don't know if I'm overreacting because I'm stressed but I'm kind of upset that he didn't even ask what was wrong, just said goodnight and not even I love you. I already feel awful and that made me feel even shittier. Do I have the right to be a little mad? Because I know that tomorrow he'll try to make me feel guilty for being upset because he's "sooo busy" with friends...
