How do I avoid my guy friend while not destroying our bond?

For context, I've shared this that my guy friend had been hospitalized with a broken bone. I did not reply to him because i got upset but when I did, he was worried if I was okay.

Now, he was already scheduled for operation and he still was able to ask how i was, how was my stomach cause i got sick in the past and he was checking if it came back but the catch is he is the patient and with a broken bone, he is supposedly the one to be asked. I did tell him that. He also told me to check up on him before and after the surgery which I did and I got so exhausted after. I spent all my efforts to be motivational, caring and he did thank me and was very sweet on the messages, but I grew cold after the surgery.

I just got so tired of the emotional neediness and I'm not an emotional person. I just did that to help him. I know he also helped me for about 4 months always taking care of me and always asking me how i am and giving tips how to be well and visiting me in the hospital but I just find that I am already emotionally exhausted.

I feel sometimes like we both are treating each other emotionally as that of a partner's but the catch is he already has a partner. So i wonder why is it that I am always the one he goes to when everything is not well with him?

Right now, he seems to have noticed that i am growing cold but I can't help it. He seems to be asking a huge emotional support from me and also acting like he has emotional investment on me. Imagine he is the patient and is scheduled for surgery but he still ask how was my stomach? I really don't know what to think but I want to save the bond we have, the problem is that once I remove the barriers, he will go again and emotionally attach to me.
