personal trainer- creepy or am I imagining it?

I recently had a consultation with a trainer on zoom (I was sick so we pivoted to an online initial meeting).

He asked me what medications I take which I thought was weird but shrugged it off. Otherwise it was a fine consult, he seemed excited to have me come in to train.

I went in and we did an assessment of sorts. part way through the session he said “you’re exactly how I thought you’d be!” I asked what that meant he said “Oh you know like our conversation went really well, we vibed” (something like that).

he kept bringing up that I looked familiar. Eventually he said I reminded him of his friend and he said her name and sighed about her in a weird way.

Through out the session he brought up multiple times how he “is in recovery” and attends meetings.

He kept asking me about my tattoos (I have many) and I found it distracting.

There was just a general weird almost flirty vibe to the whole situation— and it left me with a weird gut feeling.

I cancelled my second training with him, and since then he has called me two times a day, two days in a row. He has sent multiple texts and also emails trying to work with me and my schedule to have me come back in.

Does this sound weird or am I over thinking it?
