If you find yourself in a relationship with a fanboy and it looks like it could turn into marriage, think about what your future financial situation will be like. I didn’t have the luxury of knowing that Ash was going to turn into a fanboy when we decided to get married, but I hope that doesn’t happen too often to other people.
Anyway, you might want to make sure that your fanboy is good enough at math to balance his bank account or he has a very nice job so he has a lot of disposable income. Otherwise, you will need to shoulder the financial responsibilities and transfer money into his bank account so he can pay all of his bills because he squanders all of his money on superhero t-shirts and comics. This will result in bitterness and cause you to write passive-aggressive notes about him to post on the internet.
