This unfortunate situation whereby you became unwell, served as a little test for this fledgling relationship and your 'boyfriend' failed. Miserably.
Take note. This is a clue as to his nature and if you are savvy you will get out, pronto.
By way of contrast, when I had been dating my then boyfriend* for a little less time than you've been seeing this individual, a little test of a similar nature (ill health) cropped up. We'd only seen each other a few times really and though things were going really well, I messaged him to explain that I was going to be in no fit state for company for at least a week or two and in so many words that I had no expectations from him to help out or even see me while I was going through this (I was recovering from a minor but very painful surgery). He completely ignored this, insisted on sharing my care with my mum and arrived at my flat with Marks' food he could just stick in the oven (he didn't have much idea of cooking!), along with treats, nibble things, juice, DVD's, magazines and more importantly, an enormous attitude of kindness and I CARE ABOUT YOU.
Theres no reason why your chap couldn't have made it clear to you that, regardless of whether he actually could drive you home for whatever reason, he cared about you. The fact that it seems he absolutely could have driven you home (from what we've been given to understand) just makes it awful. As for 'what you gonna do then?', just no.
