Questions: Guy's Behavior

I have a huge crush on a guy at work. We have been talking for a while now and he says good morning to me every single day. There are tonnes of things that he has said/done which make it seem obvious that he is into me. However, I’m not great at reading guys. These two separate interactions stand out to me.

He pretended to trip when he walked towards me. I said, “did you just trip?” And he smiled and said “yeah, I almost fell head over heels into you, I’d have knocked out a tooth”. I then said “please don’t do that” and he said “I will next time”

I asked “are you going to fall into me?” And he smiled and nodded enthusiastically.

In my opinion, his choice of wording seems too oddly specific

Then the other day, I jokingly asked him “why do you hate me so much?” Which was clearly a joke. He paused, looked at the floor and said quietly without smiling “I don’t” and then proceeded to grin and tease me.

Do you think he has feelings for me?
