This is the desperation that happens when a party's voterbase is dying off and, thanks to their own fucking policies, have no future generation to replace them with.
Her plan b probably is delaying article 50 and represent her same deal at a later date,
Indeed. The thing people voted for was so poorly defined that it's impossible to say what people actually voted for. Everyone had their own idea of Brexit. Whether or not those ideas were realistic or good is a whole separate matter though.
She can withdraw, and hypothetically trigger it again at a later date. That wouldn't remove any of the complications and complexities of a Brexit however, so I'm not sure what good it would do for her. The EU is also open to allowing a delay if they can show meaningful progress can be made, like with for instance a new general election or referendum, but I don't think May's keen on those options.
Only with the consent of the EU, and they've suggested they'll only do that to give time for a democratic solution (i.e. a general election or referendum). If it's just to attempt to renegotiate or spend more time on internal squabbling then no, probably not.
Currently it has cost the country £500 million a week (£26 billion a year), and that's before any of the other shit has hit the fan, so I think it's far to say A LOT
