I think you need to speak to some professional (your mum). None of us are going to give accurate advice because we don't know how you two act together or what you have been to. All of us are going to base our advice one shit we've been through. Some shitter than others. But if you really want advice here's what I have to say
Communication is absolutely crucial in a relationship. people misunderstand and things fall apart because people don't have communication skills. Say it to his face. You love him, I can feel that. I assume he doesn't think of you as annoying or a bad girlfriend or wants to break up. so just tell him you are worried. He won't get angry for being caring. That's one of things I'm bless to have, a girlfriend who will care about me. Don't text him cause it can give off the wrong vibe. At the very least call him. He is busy? too bad. You gotta do it. Someone told me arguments are painful, but they bring us closer. I don't know how far that quote goes, but it's true. I usually do hug my girlfriend after a fight.
Go up to him, bring him coffee, some bread, and a kiss. chat. its healthy :D

It sounds like he needs it and you care enough about him.
Give him a little air.
