persumably having a vampire girlfriend would result in you becoming a vampire so its a bit hard to say unless I know if its the modern being a vampire is super easy with just some twinkling and limited diet or absolutely horrible ancient vampire where you lose your soul and sorta become demonic and twisted and light causes you to die a horribly firery death. I mean giving she loves you kinda sounds like its the modern easy to be minimal bad effects vampire.

Ok so, since some stuff isn’t covered by variables, I can pick them.

Change gf into vampire (after consent). You’re of vampire is the ones from Twilight. Stupid series imo, but the vampirism has the best rewards with least downsides. You live forever, you’re at your peak forever, you don’t have to drink human blood, you can eat whatever (but you have to horf it up but you don’t suggest it so I guess it tastes the same). Oh and you get super powers and even a special power unique to you.

Downsides are not getting drunk (can probably do other forms of libation) and you … Sparkle in sunlight, but I’m cool with that.

Get turned into vampire, turn family, friends into vampires, and then save (with some exceptions of certain billionaires and politicians and so on) humanity from the threat of death. Drinking only animal blood is way better for the animals and the environment, could synthesize synthetic blood, people would care about the long term effects of pollution in the planet. Create an environmentally friendly eternal vampire utopia. While still getting to eat garlic bread if you really want to.

Easy. Garlic bread.

Already got a wife who loves me. And if she were to pass away, I have a lifetime supply of garlic bread. What sane woman wouldn’t want access to that?
