He's on Match.com

[Dom R]

PS: you probably dont know when he put in the "single with no baggage" thing. yes, it's hurtful. but he may have put it in 2 months ago.

as far as him checking...
he is not committed to you at the moment. you know that. you are expecting committed behaviour from him.

expectations like that will always lead to unhappiness and disappointment.

besides which.. you dont know what he's actually doing. whether he's "just looking", vs setting up a date for himself.
Right now, all you can be really sure of, is that he "looked".
