<human>: Could you distill the essence of the text into 1-3 sentences?

First off sorry for the spelling and grammar I am posting from mobile. 
For 7 weeks now I have been seeing a cool guy. We met last June and quickly became friends. We have a lot in common and we are both really hard workers. My issues came up yesterday. I knew he likes to drink which is fine, I don't really drink but I don't judge people who do. Yesterday he told me a story about how Sunday night a mutual friend of ours got really drunk and started driving him and some other people around. He said they were doing 40 mph down a 25 and taking turns super quick and hanging out the windows. Then he told me about how he kept telling the mutual friend to pull over but he wouldn't. He said the mutual friend ran into a car and ended up totaling his car and did a hit and run. I got so angry at this but couldn't put it into words. He said after that he got out and went to his car and drove home. But he was drunk too he drove just as drunk as the mutual friend. 

After this whole story he noticed how I was itching a rash on my wrist and he said he had something else to tell me. He said he had scabies and he probably gave it to me. I have had an itchy rash but I thought it was just a stress rash. We haven't had sex but scabies is still an STD. I got super grossed out at this and just left.

Today he texted me that he was really really sorry. And I replied "the scabies thing is gross but whatever, I am angry about the drunk driving. I think it is an incredibly selfish and dumb thing to do". He never replied back.

My questions are is he worth it if he decides to stop drinking and driving and if I should be mad about the scabies.
<bot>: A guy I really like told me he drunk drove. He also gave me scabies. Should I continue to see him if he promises not to drink and drive again?
