ok, then what do you think the endgame would have been had they stayed the course on that relationship? A merging of the two mythos? A situation where Lois and the rest of SM's in house romance life would be stuck in competition with Wonder Woman or a situation where Steve and the rest of WW's in house romance life would be stuck in competition with Superman?
They could have used Flashpoint as a new beginning. instead they went in an unsustainable diection and had to double back. It was a mess and a missed opportunity.
