The fact that her mind can do a 180 whenever she feels like it. I've found the phrase "ok that sounds good" to work for me. Be careful of the 360's. That's where you will get yourself into trouble. I don't recommend those for an amateur.
Vague question, but what do we value, deep inside? We're very "security minded". We want to know that we will always have a roof over our heads & a caring home. We want to be with someone who loves us despite our flaws, as we typically love others despite their flaws. That our children will be wanted & protected; that we need to live without fear of being abused, beaten up or raped. We want men to truly believe we're as important & needed in the world as they are & treated with respect for our contributions. If a guy cannot help protect us from harm, or support us as fairly as they support each other, then we look elsewhere for love & acceptance. It's sad that after all this time women apparently still need to clarify & justify their contributions & value.
