I'm going to pretend to love my bf for a year then dumped him
Why would you lead your boyfriend on?
I'm acting as a sort of social experiment, I want to know how one would be treated if one pretends about his/her true self
While your reasoning is interesting, it is highly immoral and unethical to play around with human emotions like this. You should never use people for such experiments, no matter what the reason. You are harming someone greatly like this.
I don't mind but if you going to judge me, at least get my inspiration right.
Well no matter your reason, intentionally hurting someone is always wrong no matter what. I think you should just abandon this idea of a social experiment.
