"time heal all wounds"

"Time heals all wounds." how true is this statement? everyone always mention it when something not good occurs. for example, you are ditched by your boyfriend and people come and console you saying time heals all wounds. Scenario 1: 10 years later, you are still single and your ex-boyfriend has a girlfriend and they are spending their lives happily. then are you sure you will be okay when see such situation? are you sure time heals all wounds? or your wounds are pricked and deepened this time? Scenario 2: 10 years later, you are still single and your ex-boyfriend has married with his wife and has a cute baby of theirs as well. Does time heals your wounds? does your wounds still hurt? Scenario 3: 5 years later, you meet a guy that is much nicer than your ex-boyfriend and you fall in love with him and decides to marry him. so is it time have heal all wounds? In fact, theoretically time does not heal all wounds at all. it's simply nonsense and it's not proven scientifically at all. It's the events that happened within the 10 years, not the 10 years time that heal your wounds. it's that your ex-boyfriend has married a woman and given birth to a baby which makes you give up totally and thus you have no choice and find another guy to fall in love with. therefore, time is not a factor in conclusion.
