I read this line and thought that this is a phony letter. But then, you might be right.
She's correct though. There are men out there who are intimidated by successful women and will avoid her. Too much work, maybe she will have standards that they cannot meet, she's not going to fall for their lines, maybe they are not successful enough in their own lives. A smart guy will know when a woman is out of his league.
Then again, also consider that some men cannot function in a relationship with a woman because they simply need to dominate and need a submissive female to stroke their egos all the time. Seen plenty of those morons along the way as well.
OUR success? Is this a sisterhood thang? Stay single lady. You want to rum a man's nose in your success. Stock up on Stauffers!
