Surprise him. Sometimes it's really hard to to that because you don't know what they would love as a surprise but if you've been together for a while you would have a rough idea of his interests :) What miss Hippie said is very true, guys love watching movies with girls and being close to them (I'm not sure about the cooking though :/ :P) I think what you should do is buy him a get well soon card with some chocolates or something, and give them to him in person :)
Hope I helped Jon
Cook for him, make him his favorite food :) Bring a movie over and cuddle, ask him what you can do to make him feel better :)
