It made no sense to him, but he understood her desire. Understanding didn't mean agreement, though. He was not her parent. He wasn't holding her back. Her parents had been selfish, and so had she, and like remembering a dream he once had, he'd had similar desires, but at least he'd been respected. His wish for escape had come true in a way that had taught him his selfishness.
If something wanted to hurt her, the distance he was keeping meant she would be hurt before he could do anything about it - but hurt and wounds was not the thing he was concerned with. She would mend. If something wanted to destroy her, it would happen quickly. There was no blood loss now, no fading of life. She would be alive or dead. The only thing his presence meant was retaliation for what had happened to her.
He'd always known this, that following her was nothing to do with being her saviour - though he might've been lying to himself a little. Funny, how he did that with both her and Lazarus. The latter a lot less in the past few hundred years, but there were times when he caught himself putting blinders on his own eyes. Love could change the quality of existence in many ways, no matter how young or old.
He sent to her the message that he wasn't her safety net, and offered her his emotions on the matter - impassive analysis coupled with a magnificent depth of sorrow. She hadn't needed him since after the first few months. He was only with her because she wanted him. Once that changed, he would leave. His sire had both ignored him and overstayed his welcome. Cicero wouldn't taint their relationship in such a way.
Then he sent her his opinion on her relationship with her parents. Both they and Ami been clueless and selfish, not one of them willing to respect the wishes of the other. To learn this amplified his doubts that he and Ami would remain together much longer, not because he would drive her away, but because he felt that she prized her perception of independence more than she prized the love of others. He knew she didn't need him. He'd known for a long time already - before even she'd reached the conclusion herself. She'd already proved her independence and strength over and over and over. How many more examples did she need before she could accept a relationship with others? After sending her this message, he decided it was time she heard his voice.
"Wanting to be close to you is not about you, it's about me. It's not to protect you, because I no longer can at this distance." His voice was soft. There was no plea in it, no patronising tone. He was just telling her the truth. "If you are intolerant of the closeness of our connection, you won't have to leave, because I will. I will not stay with someone who abhors my touch, the sensation of me nearby. You are angry with me because I wish to be close to you, like a married woman who can't stand the sight of her husband."
