If you want a long and healthy relationship, then you have to open up to your partner and part of that opening up is exposing your weaknesses to her,
That's pop culture thinking. Nothing good comes out of appearing weak. It does not bond nor grow love. We mention our weaknesses to our therapists and healers (they don't bond to us), women are neither our therapists nor healers. They are our lovers.
Unless she's neurotic and will cling to you regardless, or unless she's a dominating control freak, what will occur in time is that she will escalate her "masculine" self to compensate, and that will change the dynamics of the relationship you now enjoy. It could even end it as her inner resentment builds at being made to be the bedrock.
She wants YOU to kill the spiders.
She wants YOU to get up in the middle of the night to investigate the strange sound coming from the living room.
She will resent you if you're afraid and ask her to do these things instead.
The above could be actual, or these could stand as metaphors for other circumstances you face in your life.
The bottom line is that she wants to trust that you will take charge. That you will take on the "masculine" role, not the "feminine" one. That she can relax knowing that you're making the decisions, knowing what direction to take. Otherwise, she feels you floundering and she will have to take charge, and will not be able to relax.
It's not only in your words, but it will be sensed through your eyes, your body language, the tone of your voice.
I hope you're not the kind of person that's so indoctrinated so as to take this description I just gave and knee jerk see it as describing a macho, domineering male, because I'm not... but that you understand I'm talking about male/female polarity.
So watch out how often you express your ambiguities, your doubts, your fears and concerns, and how you communicate them, because, silently, she's taking notes.
Anyway, what you're describing isn't "communication" but that of having certain relationship skills that handle conflict, such as not calling names, bringing up past grudges, going off topic, no blaming, no demonstrations of temper, and knowing that compromise has to be a win-win, not a win-loss.
You may also have been either lucky or smart in choosing a person with whom you don't have too many arguments. However, do watch out for the "conflict avoider", the person who appears to be agreeable but is actually silent about their disagreement because they're too fearful to engage in a debate. From outer appearances, they seem fine, but they build inner anger, frustration, resentment, depression and it's one of the top relationship killers.
