If you’ve ever wondered why you think, feel, and behave the way you do in relationships, attachment theory explains it better than almost anything else.
Originally developed by John Bowlby and expanded by Mary Ainsworth, attachment theory shows how early relationships shape adult connection patterns.
The books below are the ones that actually help — not just theory-heavy waffle, but practical, readable, and genuinely useful for both personal insight and counselling work.
