Relationship advice:I feel suffocated by my boyfriend's constant presence. How do I tell him I need space?

We only started dating on Valentine's Day and we happen to work in the same office so I see him 4 out of the 5 days I work and he wants to monopolize as much time with me. I understand that I should appreciate that he wants to spend so much time with me, but it's too much. Today I ignored one of his calls and when I called him back he told me he drove by my house but I wasn't home. I also had an email, a voicemail, several text messages and a message on facebook from him. He says I make him happy and I feel like he's too intense and suffocating.





How do I tell him nicely that I need my space, every time I run it by my friends they say I sound mean. I do like him, I like being with him, but not all the time. I don't feel ready for a relationship but committed because he seemed upset that I hadn't said ';I'm your girlfriend and we're exclusive.'; I was exclusive to him, I just didn't think we needed the titles and now everything is too much.
