Fwb might still have feelings for me

So me and my fwb ended things in march and havent done anything since, but recently a mutual friend has been constantly bringing him up all the time to me and saying like “oh blahblah has a crush on you” but then says hes only joking ? Im really confused because some part of me still has feelings for him and if he still felt the same way i would definitly be into starting things up again, but dont want to bring it up incase it is only teasing?? What should i do!
