I've taken both approaches and, at least for me, confrontation left me feeling dirty. In one occasion I could see the pain and sadness in their eyes, which made me feel like shit because I genuinely loved them, and on another I got to see exactly how little they cared about me which also gutted me. We can fantasize about how good that closure would have felt, but it's never a guarantee. To me, it's better to safeguard the pieces of my broken heart before irreparable damage is done.
