She expresses interest in your romantic life
Another crucial sign that a woman is attracted to you in *that* way, is that she constantly asks you about your romantic life and history. She could do this because she wants to know everything- from your very first kiss to your first and biggest heartbreak.
She will also be interested in seeing photographs of all of your exes, and even ask intimate questions about your relationships. You could even catch a glimpse of her envy for all the women you’ve dated in the past. If that’s the case, what better sign that she’s into you do you want?
