The only thing I would add is that people will post stuff on the internet that ppl before used to just think about. But never actually mention to their partner. The 'small stuff' that was mentioned. Sites like this can sometimes just be a way of thinking 'out loud', in writing.
I'm not sure if that's a pro or con for this kind of site. It probably depends on the person and how susceptible they are to blowing a small thing out of proportion.
I think you should make it a joke:
him - "Did you miss me?"
you - "Did you miss me?"
him - yes
you - not really; but its only been 86400 seconds since the last time you asked me that.
Second thoughts can generally be amended with judicious action; injudicious actions can seldom be recovered with second thoughts.
