what should I do?

Cl

My boyfriend always pretends to be fine but occasionally his depression and suicidalness will be very apparent through drunk messages he sends me.

I can’t seem to get him to get professional help, and he tells me to “not concern myself with his well-being” and “don’t care about his feelings”

I don’t know what to do. He’s my best friend and I love him but part of me thinks we’ll end up breaking up because of this problem eventually
