Would you be okay with your boyfriend having a beera with a girl he thinks is pretty?

My boyfriend drunkenly texted a girl last night that she was pretty, he doesn't even remember sending the text. He owned up to it, apologized, and asked if I'd be ok if he set back and had a beer with her sometime. I said i'd be fine as long as nothing happens, and he reassured me nothing would. Truth is, I'm not entirely comfortable with it.
