I think it's great that she's doing something for herself. She doesn't have to fall in love again immediately (I'd rather she didn't), what's important is that she's not leaving herself in a position where all she does is rely on others. This way, after three lifetimes of essentially living the exact same way (as a villager in a small village), she'll be able to experience something different. "Wait for me" shouldn't be equivalent to "let your life stagnate for years on end while I go out and see the world and meet new people" anyway. He wouldn't be the same even if he did come back, why should she be?
