Is it possible for someone to fall in love even without knowing it?

For context, I think my guy friend is falling in love with me but doesn't seem to know it. I just took the hint more seriously right now because he is asking for emotional support from me when he underwent an operation and said to contact him before and after to check on him.

It wasn't a simple motivation. I had to show my caring side and we promise to eat out together after. I said I can't wait to him getting better and he said he can't wait to eat a lot. There was more and it was really intimate, sort of a life and death situation and there was us trying to defy it.

He literally copied the same situation when I was in the hospital and also need to undergo an operation, he also was my emotional support back then but the difference is I didn't ask him to check on me. He just did. Although i did message him that I got hospitalized.

I think this all started when he constantly became my "rescuer" when I got sick and always checked up on my health frequently. He then ask about my routine, tells me what to do, guides me, creates an excel sheet of what i should eat. He especially loved to be complimented on and he does also compliment me often.

In person he is very silent and can't look me in the eye but on messages, he is very sweet and wants to take care of me all the time. He tells me if I did well and just exhibits signs of emotional dependency.

If I so much as not talk to him for days, he says he gets worried and asked me if I was okay and he asked me this when he was the one in the hospital.

The dependency, frequency of contact and the emotional support he wants from me tells me there's something there but I fear that we may be in an emotional affair. I know he had a girlfriend last year and I think it's still going on. My question now is how can I remove myself from this? Is it possible for someone to fall inlove even without knowing it?
