<human>: Condense the text into a few key points

Hi Reddit. I am a 23 yo male who got out of a 1.5 year relationship about 3 months ago. Two weeks ago I met this girl [22F] through okcupid and ever since we have been hanging out all the time. Sleeping over seeing each other at least every other day. She helped me move. She came to see a hockey game I played in. 

She said to me yesterday that its like we've known each other for months..

Now we haven't had sex but we've we have fooled around sexually including orgasm. She wants to be more committed before we have actual sex. Which I'm fine with. 

Here's my problem. I want to focus on work, exercise, hockey,and  my friends who I neglected during my last relationship. I really like this girl but we've seen so much of each other I'm starting to feel pressured and like I'm in a relationship. I know that once I start feeling this way it will progress unless I have significant distance. 

I must mention that she works in the building down the block from me, so I can and have seen her a lot.

How do I end this tactfully? I've only known her for two weeks but I'm not really interested anymore. Do I send a polite message or phone call? I don't need this drama in my life.

We are supposed to go out tonight but I want to cancel and just have a day to myself with out feeling this way.
<bot>: seen a lot of this girl I've been dating the past few weeks. Now turned off and want to know how to proceed.
