Is it okay to date an ex situationships friend?

I don’t even know how to explain this, but I went on a few dates with a co worker (we’ll name him Dave) couple of months ago… we didn’t even get physical, the most was literally peck on the lips after our last date. But it didn’t work out and we are cordial at work. Mind you, I’m really good friends with Dave’s best friends girlfriend, who I also met at work, and recently she told me that when Dave’s buddies came into work, one of his friends saw me and was interested in me. And I’m not gonna lie the mutual attraction is there. Is that okay on my part to be interested or go for it if his friend takes it further and asks me out? Clearly, I wasn’t brought up to the boys by Dave so it feels like it wasn’t serious on his end, but I also really don’t know how this bro code/girl code works if it never got serious between me and Dave. Thoughts?
