I Feel Sad

It's been like, a year but I can't get someone out of my mind. We talked consistently for the better part of three years before she told me she loved me and wanted to live with me. Only for her to never reply or reach out to me again, making me wonder what I did to screw that up. It doesn't bother me too much anymore but it still makes me sad/ depressed when I think back to it now. I can't help wishing it had ended differently... sorry to wallow in self-pity. I hope anyone reading this has had a great week so far.
