Would you put yourself or the person you liked before yourself (if a situation required you to put them before yourself)?

My boyfriend was really upset earlier and even though I have a lot of schoolwork to do, I just neglected it so he would feel better.
I should be doing it now but I'm curious what other people would do.
When he found out that I was putting things off just to be there for him, he tried to make me go do them but being stubborn has its perks.
