Johnson was ambushed in parliament on Saturday by opponents who demanded a change to the sequencing of the ratification of the deal, exposing the prime minister to a law which forced him to request a delay until January 31.
So, it's complicated, events are fast-moving, and things could still change.
The law also compels the British government to accept any extension the European Union offers, so a no-deal Brexit will only happen if the bloc refuses.
In his latest Commons defeat, Mr Johnson abandoned plans for a meaningful vote on Saturday when MPs backed a move forcing him to ask Brussels for a further delay. Had they voted in favor, Brexit would have happened as scheduled on October 31. But on Saturday, lawmakers voted to delay their backing for the agreement until the legislation needed to implement has been passed. In practice, that meant that Johnson was unable to get the clean yes or no vote he had desired.
"I will not negotiate a delay with the European Union", he also said in parliament.
Going forward eyes will be on whether the Speaker allows parliament to vote on the Brexit deal, however, given that the same issue can not be debated twice in one sitting, it is likely that Speaker John Bercow will unlikely allow for another parliamentary vote.
Johnson sent an unsigned letter to the European Union late Saturday seeking a delay to Britain's impending departure from the bloc, as required by law.
Britain's parliamentary speaker John Bercow told the government on Monday it could not again try to get a vote on Prime Minister Boris Johnson's Brexit deal because it was posing the same question to parliament twice.
That also gives British lawmakers another chance to scrutinize - and possibly change - the Brexit departure terms while the bill is still in Parliament.
With Brexit up in the air, the bloc's ambassadors decided on Sunday to play for time rather than rush to decide on Johnson's request.
The government plans to introduce its key Brexit bill later in the day Monday, with lawmakers holding a first round of debates and votes on Tuesday.
Alternatively, by the end of this week, he may have been forced to concede, and to push for a general election to break the impasse in Parliament. MPs were supposed to approve the nearly-600-page deal despite having only received the text that morning and despite there being no economic impact assessments of it-because in the Wild West that Brexit has turned Britain into, who needs them?
Steve Baker, chairman of the Conservative Party's European Research Group pro-Brexit caucus, told BBC Radio on Monday his colleagues are prepared to compromise to get the United Kingdom out of the European Union on October 31.
"The risk of leaving without a deal has actually increased because we can not guarantee that the European Council will grant an extension", explained Michael Gove, the Cabinet minister who has been tasked with No Deal preparations. That's because the current anti-no deal legislation, passed by rebel lawmakers in September, was written with very specific reference to the October 31 deadline.
