Not necessarily, It could also mean she began to see through their bullshit, their lying, their manipulation, she began to find the strength that was always inside her, that her partner worked hard to destroy, It could mean that she began to learn about narcissism, love bombing, gas lighting, trauma bonding, devaluing, discarding & reverse discarding, It could be that she just has no more tears to give because she is tired of being hurt, repeatedly, for so long, It could mean that she is finally choosing to put herself first, instead of placing the wants & needs of her partner above her own,
No offense, but many of us choose to be single for the remainder of our lives because we have been so thoroughly destroyed by someone who said they loved us.
