Cosmic Rose,
Being a person on the other side of the relationship I can say communicate what you feel. If you have trouble saying the words, write them down. If you feel this strongly about him you should say so. I know the person I care for struggles and while at times I feel at a loss for what to do, I can only hold onto what was shared with me, providing that with patience and consistency.
If you are not as outgoing, maybe sharing that will help you two strike a balance. If you are honest about what you can give and what you want to achieve, it gives them an understanding of your position and what direction you can move it.
Although communication is the toughest thing sometimes, if there is respect and care between you both, you may find it will work out. And if not, while it is sad, you have learned some things in the relationship and know in your heart you gave it a shot!
You sound like a lovely person and you are very much worthy of someone who will love and respect you!
Good Luck!
