Of course you can give them together. You don’t have to worry about so much. I think what your boyfriend wants now is your nervousness and
care, so he doesn’t care about you giving them at all. Whatever flower or fruit he has, even if it is just a small apple,
help him peel it and feed it to eat, he will feel very happy
As for blessings, that is your blessing He is well. You are blessing him by posting this question.
I hope it helps you. I hope your boyfriend will recover soon and be safe and healthy
