Why would my boyfriend be so unsensible?

I texted him to ask him what he was doing tmr and told him I felt depressed and suicidal due to my upcoming period. That I couldn't cope with these monthly hormonal inbalances. All he answered was that he'd visit some relatives tomorrow. Not asking me how I felt or how to improve my mood. What's wrong with him?
