What can I do to make this work?

I am dating this amazing guy named Trey. I just got over one of my ex boyfriends Jearad, but I know I am 100% done wih him. Anyways, Trey is seriously the best guy I have ever met I know that this is not all an act. He may be a little shy but he has really opened up to me. We can kid around and have fun with each other which is great. He loves me no matter what even if my makeup is running and my hair is terrible. I am even comfortable enough to see him with no make up on, which trust me is big for me. I am sooo comfortable with him and I trust him. We see each other on average 3-4 times a week. I dont know what to do though… I know I have feelings for him it is just they have faded to where I cant feel them anymore. Please dont say break up with him or anything because I certainly dont want to lose him. Is there anything that I can do to like better open myself up to him. My theory on this is since I have been hurt SOOO much by guys I am sort of not letting myself have feelings for him so I wont get hurt. So I am really confused and need help on what I can do to open myself up and have those feelings back. Thanks to all who read this and I hope you can answer and give me your view on this:]
