<human>: Give me the gist of the text in a nutshell

Ok so I have this fuck buddy who I met several months ago. When I first met him, we got along amazingly. We both weren't looking for anything serious and just wanted fun. So we became fuck buds. A few months pass, and he starts developing feelings for me. He doesn't outright tell me, but he makes it obvious. I know I should've ended it then, but I was selfish. So we continued being fwb. Now, a few more months have gone by, and I think I'm developing feelings for him. I'm pretty sure he still feels for me, but I don't whether to end it or confess. I don't know if anything between us would work out well because he's a liar and a cheat. i wouldn't mind doing an open relationship, but I'm not sure if I can handle him lying all the time. What should I do??
<bot>: Have a fuck bud, he fell for me. Then I fell later on. Don't know if it'll work, he's a liar.
