<human>: Can you give me the gist of the text in a nutshell?

Here is the back story: My EX's best friend kissed me when me and my ex were still together in 2013. It caused me and my ex to breakup for a few months and during that time the best friend and I started a little fling. My ex found out about it and asked the best friend to stop seeing me, which he did. When my ex and I got back together he dropped his best friend and we dated for a few more months before calling it quits. 

I should say that before I kissed his best friend, the best friend and I hung out every weekend and I was kind of his wing-man. My ex worked a lot and would always catch up with us afterwards.

Now that my ex and I are absolutely done, the best friend hit me up and after a few weeks of texting back and forth he suggested that we meet up ---The last time I saw him we were both PLASTERED and I might have told him that I love him or want to be with him or something stupid like that? During our time texting he has made remarks about knowing that I had feelings for him/still might. I want to see him because we can get DOWN in bed. But all those feelings are going to come back harder than they already have.

I don't even think he wants a relationship and I could probably be OK with a little fling again like the last time, but I don't think I could last long. I really like this guy--like if there was a checklist of the "right guy" for me--he would have it all checked off.

I know, I know. I'm a terrible person for doing stuff with my ex's best friend. And for wanting to do more with him. Should I just shut it down before it goes any further? Should I risk it and enjoy whatever comes out of it?
<bot>: I did the naughty my ex's best friend in 2013/2014 and then got back with my ex in 2014 only to break up with the ex again and now I'm crazy for the best friend and want to do more with him.
