After that event, no one dared to bother the young lady about her choice in husband anymore. Even though many thought she might be lying, after all, how could such an alchemy talent fly under their radar, they chose to let it be. With the young lady's talent, they simply didn't have the right to question her decisions, and clearly, even if she was lying, this romance of hers hadn't affected her focus on her craft at all, so they didn't have any right to complain.
That said, many thought she just made up this husband of hers entirely. It wasn't rare for young women, especially as beautiful as she was, to be harassed constantly by young masters who saw themselves as more important that the heavens themselves. Maybe she thought this imaginary husband of hers would alleviate some of the pressure on her.
