Can we go eat as friends?

Hey guys so i’ve been friends with this guy for a while now. He’s very friendly and is a really noce person. I havent introduced him to my partner because he’s always working. Anyways, my guy friend invited me to go eat today because he’s off. But i dont know if should i go?? My bf is working today so we never have time to go out. and i’m scared of mentioning it to him because he will probably think wrong..
