So I work with this chick (only there for 1 more month so it's cool and only have been there a month) we have been out before and flirted hard she was hitting me and overall went well, talked a bit this week.

Anyways there is a guy who likes her who does shit for her all the time who is an overall nice guy and I'm pretty sure he is friendzoned.

He was with her and i was confirming a time for us to get food and retardedly invited him and he accepted. He seems like the type of guy to cancel. I like the guy he is chill but I feel like I fucked up.

Would my best course of action be to go to the dinner with both of them and go clubbing or chill downtown afterwards with just the chick? I'll either invite her clubbing way beforehand or at the dinner
