Does this sound fishy , or am I overthinking ?

My boyfriend and I live together, he lost his car so we use my car. He dropped me up today at work in the morning and took the car, because I worked 12 hrs shifts. Later today at 1 pm he texted me and told me, one of his friends, I know nothing about wants he to come over to hang out, so he won’t pick me up. He sent me some money to Uber home. I called him to know more about his unplanned getaway he didn’t answer my call. When I got home from work he called me, so I asked him, when are you coming home, he said i will let you know. Later tonight he called me talking about he’s going to be sleeping at his friend’s place because he had some drinks. I’m working tomorrow morning, getting Uber early in the morning is hard. I’m not saying he should drunk drive, but at least be responsible not to drink when he knew fully well I need the car for work the next morning for work.
