Phone call gone wrong ..

This boy I'm currently talking to birthday was yesterday and he called me saying he was on the way and while we were on the phone I accidentally texted him another boys name I'm also currently talking to while we were on the phone I didn't even notice till he said " wrong person " on the phone I was so shocked I couldn't even play it off he end up hanging up on me and later asked me if I still wanted him to come but I decline I'm so embarrassed but he wasn't all that mad and were just talking so he talks to other people also I didn't feel that bad .. idk what to do now like it made me realize I can't be doing this it's just not me talking to multiple people regardless of the situation what do i do now ? Has this even happend to somebody ? At this point I want to cut him off
