I hate people.

I hate relationships. They're restrictive and you constantly have to adapt. And after a while, they get boring.

I had a girlfriend. We moved in together. She started dreaming of marriage and kids. To me, that all sounded like death.

The time after I broke up with her was the happiest time of my life.

I vowed to never have a relationship again for the rest of my life. It's been 6 years now and the vow is only gaining strength.

Now that you know that, do you have any romance advice for me?

I suggest either therapy or just trying to see those things in another light.
