It wasn't a "terrible ultimatum". She would not have had to give up her title and she would not hav been poor.. but yes at the time, so soon after the Abidication, it wasn't going to be possible for her to continue as a working Princess, if she choose to marry a divorced man. But she could have chosen it. She wasn't ever very keen on royal work.. but she could have lived abroad for a few years, and then probably in later years, she would be able to come back to Britain and lead a normal upper class life. Her family would have ensured that she was not "poor" and she presumably had upper class friends and a circle.. the only difference would be that she wasn't doing royal duties any more. She may have had some guilty feeligns that if she left the RF's work roster and married a divorced man, she was letting her sister down.. but ultimately, it was up to her to choose what she wanted to do.. and she was 25, not 18. and if she did make what she felt was the wrong choice later, that she was not happy when she had given up Townsend, well lots of people have problems and make bad romantic choices.. and end up marrying someone they don't really love because for some reason their first choice wasn't avaialbe. She could have made her marriage to Tony work, better or she could have waited for longer to marry, and picked someone less volatile than him. it seems as if their Marriage was largely based on sexual attraction, a bit of "rebelling" on Marg's part and that neither of them worked very hard at it...
