Boyfriend”? Nobody called her that not then and not now. Even then they called her his mistress. Or gold-digger, other woman, and yes whore. But not his “girlfriend”. People aren’t that dumb. They knew he was married and had no intention of leaving his wife.
from what i read he was legally separated.
anyhow whether or not she had an affair should not matter when Trump certainly has not been pure in this matter.
But many of you will disagree and thats fine .
