How to keep my emotional self-control?

Only been seeing her for a month or so. I would say things have been going well.

Last weekend, I took her to one of my favorite restaurants in town. We also went to play some pool later on.

A couple of days later she sent me this: "I really enjoyed the other night it was really cool... and cute"

Honestly, my heart dropped. I was so happy to hear that from her. I replied that I really liked it too and asked her out. We're seeing each other this Friday.

I'm trying to keep my cool with her because I still think 1 month is far too soon to be getting serious... but I can really see it going somewhere in the next couple of months or so.

How do I keep cool about it?
