New love, confusing love.

Lately I've been confused about some things, actually just one thing: I wonder if I am capable of loving again. It's like I want love, crave affection, and yet I am scared to death that I am going to be hurt again.
I recently began seeing some one new, the first person since my break up in October, and I really like him, but I'm afraid of being hurt or hurting him. At first things seemed great, but in the last week or so, things have been strained. I feel this need to be with him, yet be apart from him in order to maintain my own identity. I have a very hard time believing that he won't run from me or throw me away. It also frustrates me that I can't get a read on his emotions. It's like trying to guess what is in a Christmas present and being extremely scared that some one bought you sea monkeys or socks instead of a diamond ring or ice skates.
He also confuses the heck out of me. One minute things are fine, and the next it feels like he's shut down or is blocking and I can't get through to him. He also says the same thing about me and I may be, I don't know.
I just know I hate feeling like I disappoint him and make him angry when I don't go to see him when I have the free time, but then I'm angry at myself for being late for things when I do spend time with him and I feel like I'm disappointing other people. I wonder if it's me, but I don't want to be just me.
I do know that it feels so nice when he holds me, kisses me, laughs and gently teases me. I love that part, I just don't like feeling this confused. I wonder if it will every really go away or if I'm just fooling myself once again.
