What are the rules?

Okay, so when it comes to on-line dating, what are the rules?  Take my situation for starters.  I met Shawn through the site, spoke via text and on the phone for a few weeks and then we met.  Although things went really good, I have to view it as, 'it went good for me' as I really don't know what his thoughts are as of yet.

As I know he had a very long and busy work schedule today, despite he said he'd call me when he got home, I really don't expect a phone call until tomorrow, might get an 'all tired as hell' text, but I kind of doubt it.

So am I suppose to stop further contact with other members, can I still talk to them?  Currently I am still talking to one of the other men that I started talking to before Shawn and I met.  Is this okay, is this proper on-line dating etiquette? 

At this time I am avoiding any conversation topic that may lead to a possible meeting.  We are just chatting back and forth as we did prior.  But if he does ask, what the hell am I suppose to say, do, etc...

Wow, this is a confusing situation.  Perhaps it's another case of just allowing things to happen on their own, no stress, no expectations, etc...

In truth, if I were to be asked if I thought Shawn would want to pursue a relationship together, in all honesty, I don't know.  Now that I am thinking about it, despite that I really do like him, maybe the fact that I am questioning everything is a red flag for myself that maybe, just maybe I am not ready to jump back into a relationship.

Okay, I am allowing my brain to go on over-drive here, time to stop and just chill!  Phew, being single is tough!
