May be because she was under age when he knew her that she couldn't sense the mate bond like he could. and she has no doubt changed a lot in the last 8-10 years
I think he could sense the mate bond with Rory but because she was under age at the time she may not have been able to feel in return. but as 8-10 years has passed she won't remember him. just a theory 🤔
"Edward, as your father, I'm not saying that Rose is bad. If your mate now is Rory, things might have been easier. But it's all in the past now."
