Charles was not considered "divorced" at the time he married Camilla. Charles' wife had DIED...and that made him a widower....and perfectly free to marry again under any church's laws....including the Church of England.
One of the things that simplified Charles being able to marry Camilla is that Charles already had two sons .....and so had provided the UK with suitable heirs to the throne. Additionally, he and Camilla are far too old to be having any more babies. So, not like succession to the throne had to be considered as a factor in their marriage.
There is such a thing as a morganatic marriage....which is a marriage a royal makes...with the condition that the wife will not share the titles of the royal...and that no children born to the marriage will have any inheritance or succession rights.
The marriage of Camilla and Charles is NOT a morganatic marriage.....so, technically, when Charles becomes King....Camilla will share his titles...and she will become Queen Consort. There is nothing in the laws of the UK that can prevent Camilla from, technically, becoming Charles' Queen Consort. She may choose not to call herself "Queen Camilla":....but, correctly and technically, she will BE Queen Camilla whether she chooses to call herself that or not.
Since probably two-thirds of the Brits have a divorce and second marriage in their families....I think they are being a bit hypocritical to act like it is such a horrible thing for Camilla and Charles to be married...or for Camilla to become Queen.
Camilla behaves exactly correctly, acts like a lady, and takes a second place to her royal husband. One can tell that they are very much in love, and one can tell that they have a peaceful and happy home. She is not a publicity hound..nor does she ever seek any sort of attention for herself.
I so admire Camilla....she is simply happy to be married to the man she has always loved....and has just ignored everything nasty said about her....and been content to be the one Charles loves and was willing to fight to marry.
The two boys love and respect her not only in her own right....but because they love their father and they can see how happy it makes their father to be married to her.
I don't understand all the dreadful, selfish gits who would deny those two people something that they do in the own families all the time.
