How do I not get too attached too quickly?

Whenever I start talking to a guy online, I'm more laid back, but I would start paying more attention to him the more we talk. By the time we'd reach the one month point, I'm usually attached since I'm used to chatting with him so often. However, that's also when the guy starts withdrawing.

Do I get attached too quickly? How do I prevent myself from getting too attached?
