How do I keep up with a guy who moves too fast?

Guy is just really way too fast. We've been talking for 3 months and he on the first day had been asking a lot of hypothetical questions and kept calling and texting. Lately, we would have already ended up not talking except he chanced upon seeing me across the street.

Because of that, we got to talk again and it turns out he got mad at me a lot. Some of his complaints were:
1. I hardly text
2. I deactivated my fb when he need me the most. I suddenly disappear
3. I don't want to call him with sweet names or call exclusive pet names.

My complaints about him

1. He moves too fast

2. He is clingy

3. He needs to text and call almost everyday.

4. Very sensitive of my words and my emotions in text. He gets mad when i become "cold"

In fairness to me, i really take time to fall in love and I thought 3 months is short and that i usually end up loving someone around 1-2 years. I also don't like to message often.

I explained this to him and I notice he really overthinks every message I say to him. It feels like I'm being judged. Yesterday we had 2 hours of being sweet and a mix of another 2 hours of fighting explaining my side and how I usually do not commit but I'm trying to. I cannot even say the pet name he thought of.

He, on the other hand, already asked me if he has a chance. Take note we have just yet to have a date. Although i know some stories about him. How in the world can i survive this? He keeps getting frustrated and says let's stop this and then we repeat the next day. He also keeps asking assurance from him, i give and it feels like it's not enough. He says he gets headaches because of me but I complained and said he keeps finding faults in me.
