I had a similar thing happen to me but in my case, I wasn't friends with benefits with my ex. We just had sex once after we had broken up and it made me realise I didn't want to be with him anymore. I realised all my previous feelings for him were gone and it made it so much easier for me to get over him, which at the time was something I thought could never happen lol.
I think in your case, you should remove yourself from the situation for a while and then see how you feel. If you start to miss him, then you'll know it's because you were seeing him regularly. If not, then you'll know you're getting over him. Good luck!
