Hello Margaret, and a warm welcome to the site.
If your employees or those who are employed and your their boss make comments about you, they have no right and try and hold your head up high, whatever sexuality you are is of no business to them, and if they cheat and liar that's much more of an instance that they should be worried about as they can't be trusted.
That's much more different than you believing yourself to be a lesbian, that's your private life and no concern to them, but if they are dishonest then their jobs are on the line.
Please stay strong, they have more problems than you ever had and remember you're their boss.
Hope you can get back to us, although I'm about to log off but will keep n eye out first thing in the morning, as I start at midnight.
