very much agree with healing4me...the non-threatening 'is everything ok?' is a great opener. Nothing else, btw. No 'I haven't heard from you in 3 days' etc. JUST the first question and then leave it.

If he answers then I definitely suggest asking to meet or at least cam so you can see if he really is who he purports to be (dating sites are notorious for STILL containing a LOT of catfish). If meeting you makes him 'anxious' then he is playing a game, and at the very least has no business being on a dating site, since that IS the ultimate goal....right???? DATING????? lol

I wish you luck, but take care. It's very odd to have someone start the 'scruples' game within the first couple of messages. It's also very 'catfishy'.
