Guys, Have you ever been with a woman who at first said she was not looking for a boyfriend or boy toy,?

then changed her mind ? I've been pursuing a 53 yo woman (I'm 51) who recently said that when we went out to lunch. She also wouldn't let me pay, saying it would be too much like a date. But, she has been sending very mixed signals. She has also told me she has been married three times and is going through menopause. There have been some pretty big mood swings lately. Could the menopause have something to do with it ? Thank you.
