To the guy saying "we should consider the fact that she is immortal so her jumping off a building, is really more like harmless firting 'you will not let me wipe you. I'll get dirty again so you can wipe me." Think this is just a little love letter?
I said it before. You can’t run from away. She’s immortal. At this point just accept your fate. That being to marry her and get her pregnant. For the love of things reasonable don’t get another girl involved.
He do a good decision by not putting his dick in her (yet)
Imagine how attached and obsessive she will be if he really does that
tl;dr don't put your dick in crazy
Eh, you know, I say fuck it! Put your dick in crazy! Why flow against the current when you can just let it take you out towards the jagged falls below. Hell, you might survive, and what a story you would have to tell after it is all said and done.
