Based on how quickly you always returned to this forum after saying you would take a one year break (and after historically saying you intended to leave permanently), I have a hunch that you are checking your inbox daily.
You have stated that you don't care anymore, that it is her decision, that you will forget about her forever, but your actions and posts repeatedly suggest otherwise. It seems you have been fixated on this woman for several years - despite spending no more than a few hours with her in total across both dates you had, from what I can gather - and that you are not prepared to let go. Perhaps you could consider why - why you have invested so much time, energy, emotion and hope into someone you met so fleetingly, and someone who evidently perceives your encounters differently.
You have said that she is exactly your type in terms of looks and personality. The physical attraction I can understand, but that is it. How well could you possibly know someone you met on a dating site and had two brief dates with? It seems you have latched on to this snippet of herself that she has shown you - which is probably miniscule, considering the brevity of your interaction and the fact that most of us are guarded when we first meet someone - and then created a narrative around that, about what could have been and what kind of person she is and how she must have been special. In reality, she is a stranger - a stranger you spoke to for a couple of hours twice, four years ago. A stranger you felt attracted to, which has seemingly snowballed into an obsession.
You have already been holding onto hope for years, after being ghosted (which is a horrible way to be rejected, but it is a rejection nonetheless). And chances are, the woman you yearn for is not the one you met, but rather the person you want her to be, the person you have built her up to be and the person have been searching for all of this time.
Instead of spending so much time pining after a phantom and chasing down a ship that never even sailed, perhaps it is time to focus on your reality entirely, instead of with one foot always keeping the door ajar for someone who will never open it. I know it is easier said than done, but I think it is beyond time to loosen your grip on the part of you that is clinging on to this person, thinking there could still be a chance.
You can agonise over the details and speculate why she stopped talking to you and blame it on your shyness, but the reality is there are many potential possibilities, and you are only keeping yourself trapped and rubbing salt in a gaping wound by revisiting this over and over, instead of tending to it and giving it any opportunity to heal.
