Should I be honest ???

My guy and I have been dealing with each other for 2 years. I love him so much and i know he really does care for me and love me. We talk everyday, he looks out for me when I need but often times I wonder if he wants to take things to the next level. We aren't exclusive. I feel like he's keeping his options opened so I'm deciding its only right to start keeping mine opened as well. I'm just wondering is it best I tell him I'm going to start seeing other people or should I remain quiet about it ??? I know he'll probably be upset, but I'm starting to feel like I don't matter enough for him to want to be exclusive with me. And we've had a discussion about this before. He's "waiting for the right time". 
Added: I'm not questioning if I should see other people or stay with him. Ive already made my mind up about that and know how I'm going to handle that. I'm strictly asking should I be honest and open about it or is it better remaining none of his business ???
