That's your problem. You proceeded from a fallacy. It's an election. It's supposed to be fought to the end - on both sides. What is happening is good for the nation.
And what people like you have to understand - and clearly don't for some reason - is that it won't be Trump winning a head-bob at the wire, it'll be Trump looking over his shoulder up the track at Sham, about 400 delegates back:
Great minds think alike...

I have been juxtaposing this POTUS race with Belmont 1973 from the get go.
Trump is Secretariat and Cruz is a SHAM!
It won’t matter if Trump gets to 1237 or gets the nomination on a second or third ballot. What matters is that Trump and Cruz supporters MUST join forces in the general in order to win. Same applies to Cruz supporters (if he were to get the nomination). Both camps have many millions of supporters. Neither side can be alienated from the other and hope to win the general. This means that some negotiation MUST happen on the Republican side. It just so happens that Trump is an excellent negotiator. Hopefully, whatever the primary outcome, Trump will bring these skills to bear, and a winning team will emerge.
