Feelings are powerful and important and talking about them is a mature and brave thing to do. don't hold them in and speak them to people you KNOW you can trust. "Don't apologize for feeling something a lot"
A good judge of how much I enjoy you is not only how long I can hold a conversation with you (I have a bad habit of not talking when I have nothing to say.) but also how long I can sit in silence with you without feeling uncomfortable.
