"MMmm I don't remember how long ago for me.., " The Doctor sighed. He was leaning back whwre he was sitting. He looked at her "Suppose at least I had a family once." He sighed deeply. 
He didn't want to go through the pain of losing somebody he cared about because they didn't live as long as him. He wasn't sure if he could get married again. But he had no idea, He would have to see how things ended up.
The Doctor was looking at her. He seemed to be trying to figure it out.

"I'm just afraid I suppose. Most creatures don't live as long as me... I loved a few humans in past.. I just barely could admit those feelings." He curled up on the seat he was. He seemed relaxed though.
Jack was looking at him .He didn't know what to say.
