As you have trawled the registers I think this marriage has just not been entered. I cannot see them not being married, as they continued to live locally and baptise children in the same church without any comment from the incumbent. She was buried as Ware too, so I think it is probably just a clerical error, which is no help to you.
I completely agree with you and I've made a note of that and all that's been done to find it. Now I'm off to try and find her baptism.
