Do you think he was leading me on to leave me with a final burn?

When I sent him a message on fb, I told him we could make up if he's still single, and I dropped my number, otherwise he could let me know he's taken in response to this fb message and I'd respect that and not contact him again. So he replied with my first name and then said "I still have your number" then asked me where I had disappeared. Then he sent me a text on my number. When we started the conversation he told me that I've "changed" and he "likes it". Then he said "you've lost weight"
I was within my bmi before as well but a lot of stressors over the past 3 years have left me weak with no appetite.
I said "yeah maybe a bit" to which he replied "not a bit. A lot". Then he said he wanted to call me. Just like old times. When we finally got on call. He just told me that he's taken a wife and settled down.

Why the hell did he just not say it in response to my fb message? Why lead me on? Did he just want to hear how I react to this news? That's so weird. That's not the man I knew.
