That may be so...but didn't Henry have a family picture painted during his lifetime (when Catherine Parr was his wife) and Jane was painted as Henry's wife.
I am sure Edward thought that his mother was different and a true wife to Henry, and the picture probably justified that belief.
Yes, Henry did have a family portrait painted with Jane as his wife. He himself said that Jane was his "true wife".. but only because she provided him with a male heir.. and there is no doubt he felt remorse over her death in giving him that son.
But Henry was also a man driven by his passions.
Catherine of Aragon was his first love, and aside from the occasional fling, he was a true husband to her. When Anne came along, she became his greatest passion. That fact cannot be disputed, since it took him seven years to fully have her.
I have no doubt that he felt love for Jane, and probably a sense of relief after his turbulent Boleyn relationship. She was the quiet and calm one.. and the one that gave him Edward.
There was no passion for Anne of Cleves, although he did grow fond of her and they remained friends for life. Kathryn Howard was his fantasy.. young and beautiful.. he was reportedly devistated when he learned of her infidelity. And Katherine Parr.. well, she was his comfort and his nurse-maid in his final years.
His marriages to Cleves and Howard were made in hopes of producing another son and securing the succession, but his last marriage was not expected to produce any children (although he and his court held vain hope that it would) because Katherine Parr had never been pregnant in her previous marriages.
From the time of Jane's death, Henry had always intended to be buried with her.. which is why he had her interred at Windsor in the first place. But had any of his later wives produced a son as well, I'm sure that today we would also see her buried at Windsor with Henry and Jane.
I'm not saying he didn't love Jane.. I'm only saying that each of his wives, apart from Anne of Cleves, represented a different facet of his life. To say that Jane was loved above the others would be a mistake.. each of his loves was different and each relationship was entered for different reasons.
As far as Edward goes, he was only nine when his father died. Henry made his burial wishes known long before then. He chose to be buried at Windsor, and his wishes were carried out.. and no doubt this honored the Protector's family.. but then, Henry trusted the Seymours to care for Edward after his death.
