Is he lying

I’ve been fwb with this guy for 2 years. When I first met him I got the vibe he has slept with a lot of women which is totally fine and definitely had a roster going. We’ve never had a conversation of being exclusive or anything but a while ago he did said he was off all dating apps and I just thought he wasn’t being serious. We haven’t seen each other in a few weeks and weirdly we’ve been texting every day, not all sex related but about life and all. This is the first time he’s told me he’s not seeing anyone, I put so many haha’s because I didn’t think he was serious. After the last message he sent me a voice memo became he thought I was upset about him calling me easy (wasn’t upset) but he was like “ I didn’t mean easy to get you in bed, I meant easy to get along with you, it’s good vibes there’s no issues between us, I hope you’re just joking with me and not actually upset because I didn’t mean it in that way”.

Is he catching feelings? Or is it in my head
