He calls me when he feels bad?

It seems like he spends intimate time with me when he feels bad or sick
He never invites e to parties or to fun things going out
Im always like his nurse or psychologist or cleaning lady or a buyer
But im not the one who hangs out in the restaurants with him with his friends
Im not the one with who he goes to a shopping mall or other fun places
Why
Wtf what kimd of "girlfriend" am i?
Or this Is actually what girlfriend means?
He calls me when he feels bad?
