Unspoken mutual attraction in the workplace?

I work as a P. A to someone - how would I know if it’s friendly or he’s fond of me (he’s married)

don’t get me wrong he’s never inappropriate or anything like that. He’s also married so I’d never do/say anything, plus my job on the line.

we’ve worked together for a year now - our roles mean we have to work very closely together - speak often/lots of chasing about things.

it has naturally shifted the longer we’ve worked together. But it’s the last few months.

we use to catch up once a week and now it’s twice formally and then calls inbetween (he rings me almost daily and he sometimes say it’s something about work but irrelevant to me - telling me he’s late for a meeting that I don’t attend and also I didn’t need to know, then asking how I was and my plan for the day for example). Lingering on calls is recent - he pulls out the most random work question and it does sort of flag to me it’s random. I even once reeled off a list for half an hour and he said what’s next? Like he didn’t want the conversation to end as he’s never done that and we were about to go on 2 week break.

one to one catch ups can feel very intimate to me (not sure if it’s because I’ve been single that long) but he literally looks at me like I’ve never seen anyone look at me. He leans in, twinkly eyes, smiling, I've noticed him mirroring my movements - i put my hand under my chin and noticed immediately he did it and generally he doesn’t sit like that as he sits quite proud and open

prioritises my time - praises me openly in front of people as me being amazing/always says we

gives me best possible work compliments (not gushy or OTT but powerful) - I’m seen and heard completely. Sincerely appreciates me.

in meetings together I’ve noticed recently him gravitating towards me and will come to me about anything and ask the most random things - like asking for pens acting like he’d never seen my pens before and telling me needed some - but in actual fact we didn’t need any.

am I crazy?
