The love bombing stage of narcissistic abuse can be really hard to escape from, especially when there's a history of gaslighting. Too often a victim remains drawn in and stuck in a loop of "they're being nice now" without realizing it's just a tactic to keep the abuse. I agree that there are times you have to stop being nice and walk away to stop the abuse, no matter how 'nice' the narcissist is being at the time.
