<human>: So here's the back story. Brandon (26M) and I (25F) have been friends since our freshmen year of college. Last year, about 6 months after he got out of a LTR, we ended up hanging out more one on one. This led to some sexual tension building up, which we eventually gave into and both agreed to see where things would go. After a few months he ended up deciding he needed time to himself, to be single since he hadn't been single since he was 18 . Only a few our mutual friends knew we were "more than friends". 

One of Brandon's good friends from high school, Steven (25M) asked me out on a date about month after things ended with Brandon and I. I'm almost 100% sure Steven had and still has no idea that Brandon and I had been more than friends. When Steven initially asked me out, I was still getting over Brandon so I told him honestly that I wasn't looking to date anyone. 

Later in the summer until the beginning of this new year, I ended up dating two other guys, both of which didn't work out. The last one ended just after the new year which was when Steven reached out to me again and said that we should hang out. We went to dinner and I had a good time. Since he called it a hang out and I hadn't seen him in a few months, and I had just gotten out of my last relationship, I treated it as a "catch up" dinner. After that dinner, he asked to hang out again. When I agreed, he then went ahead and called this "hang out" we have scheduled for this weekend a date. 

Now since I just got out of a relationship, once dated his good friend, and I am not sure the chemistry is there, what should I do?  Part of me wants to go on a few dates and see if anything develops but it's a bit of a sticky situation with him being in my group of mutual friends and the fact that I once dated his good friend and he doesn't know that. I also don't want to lead him on because he is a genuinely nice guy who doesn't have a lot of experience with girls. Reddit, what do you think I should do in this situation?

Can you provide a brief overview of the text?
<bot>: Should I date the good friend of a friend I once dated? He doesn't know that I dated his friend last year, and I have some emotional baggage I'm dealing with as I just got out of a relationship.
