Each round of betting starts with the player after the dealer. In the preflop round, then Widget and slimshady2357 were first and second after the dealer, but they had to make the automatic 'blind' bets. As there are only three of you left at the table, that meant that you, the dealer this time, were the first one to post an action. There aren't any blind bets after the first round of betting, so it's Widget's turn to act first from now on (till the end of this hand, unless he folds).
Widget can fold (but that would be pointless), check, or bet. Checking is the same as betting zero.
