You are not alone. I dated a guy who wound up moving out of town. I’m all alone, and it sucks

Aww it is so touching how much you did care for her. Did she leave/end on bad terms? I guess it shows though, if she couldn't even say 'hi' or 'how are you?' Is it someone you'd truly want to be with ? :/

I'm sorry. There is nothing wrong with you and you deserve so much better. She doesn't deserve your time and effort.
