It doesn’t take much for me to be a kept man. A nice three-bedroom house, entertainment room, and all the Transformers, and I’m good. If I don’t have to work for a living, even better! Can she be my immortal workout partner? That’s the multiball combo right there.
I’m not the same person I was 10 years ago. Think of the differences 100 years would make. Think of the cynicism, the endurance, and the lack of need to get it right with me because he has another chance somewhere down the line.
Yeah, I mean. Look at The Doctor. 
If I loved her, thats all I’d need. To Love someone is to be with them to the last beat of your heart.
But, to the extent that me getting older would hurt her & cause her pain…I’m not so sure. If I knew that being with her will do nothing in the end but cause her pain and sadness… well wouldn’t her happiness be the most important thing to me? Why would I want her to have and live with such agony for an eternity?
I think it would be worse to spend eternity alone than to love and lose and love again - and lose again, and love again, ad infinitum…
I said I’d have children but I might not–that is, I’m not sure if I’ll ever have kids with ANYONE. But what I meant is, the person being Methulselah-esque wouldn’t influence my decision. If I loved them, it wouldn’t make me hesitate.
Likewise, I said I wouldn’t have children with them because I won’t have any more children with anyone, regardless. Couldn’t if I wanted to, not without a lot of hassle and expense. 
“Honey, please tell me about all your previous lovers.”
Yes, women ALWAYS respond well to THAT.
I don’t know why not. Maybe I’m just weird…

If she was truly in my heart.
If I could look in her eyes & see that she loved me too.
If, through some unexplainable power that defied the laws of physics, the canon of logic, the standard of common sense,
and the majority opinion of the smartest people in this country (and on this Board), I could some how find a way to make her happy.
If I could bring her smile as a field brings wild flowers in Spring (rain or shine).
…then I could deny her nothing.
The musicians may play forever, but for me this dance is only until midnight. And if I loved her, she’s the one I’d want to be dancing with when the masks come off.

I’m not sure this makes sense to me. Madame Methuselah is a lot older than you and has done this a lot more times. If she thinks she can handle it, she’s probably right.
Admittedly that brings up the issue of her psychology. Assuming she hasn’t gone batty, then surely her mind has made certain adjustments that might be distressing to contemplate. Upthread, jsgoddess worried about the Methuselah not being fully committed to a relationship because, to the Methuselah’s POV, another one is always available. It could also be that a Methuselah would be more iwlling to tough out a rough patch of years or even decades, because to a 2000-year-old person, 30 years is something they can do standing on their head.
