Hahaha! sry I found this to be funny I know it really isn't but that is completly not what I would expect, I cannot even begin to understand what that might be like, I also cannot imageine what watching Xorg, GNOME, and KDE compile might do to your head! I tried Gentoo for 3 days and I got so sick of the compile outputs I deleted it and installed Arch Linux( which might also be a good alternative as it has all the optimaztions done for you, at least all the ones I would use).
That's amazing though, that shes been able to get LFS together. I think you should truely be proud of her. You might try getting an extra computer and asking her to help you setup LFS on it as well, it might be a good project to get together. Or maybe you can even make your own distro (although that might just cause a bigger problem).
I'll be careful getting a girl intrested in Linux from now on
Girl: "What are Gentoo and LFS?" Me: "No no no dear, we don't talk about those" Girl: "why not" Me: "shhhh we don't ask questions like that about the unspeakable distros, if it says "source based" stay faaaaaaaaaaar awaaaaaaaaaaaay"
hahah, ok I'm sry I just had to do that.
Relax NinjaZombie I think things will come around, it could be just a phase.
BTW I noticed you said fiancee, thus I assume that you asked her to marry you and she said yes, thus I belive congradualtions are in order (however late) thus, CONGRADULATIONS! I wish you too the very best!
Good Luck buddy!
