if you want a relationship with a woman to last, she needs to know who you are, and she needs to feel safe with you. Emotional safety, like emotional connection, is built through the process of attuning. When a woman makes a bid for your attention, when she reaches out to you emotionally and you meet her reach, this demonstrates your trustworthiness and emotional safety. If you shut her down, ignore her, or otherwise don’t attune (especially when she is upset), she will not feel safe with you emotionally, nor will she feel safe to be herself with you.
