Boyfriend invited me Starbucks and asked if my family wanted some and I ended up paying? ?

He told me to ask if they wanted Starbucks too and probably thought they would say no lol well when we got there I asked if he was getting something and he said no, but you already have a list of drinks that you have to get. So I order and when I pull up to the window I didn’t see him take out his wallet. He ended up ordering one too. So I had to pay for everything. I think he didn’t want to pay cuz my whole family ordered lol idk why he asked them in the beginning though.
