Who am I?

Ever since I told Nemesis about my realization regarding my happiness, things have been... changing.

I'm putting Nemesis in a very critical situation, and I know that's gotta suck for her. Does she want to be the kind of girlfriend who dumps his boyfriend just because I, an ex-boyfriend who made her life miserable when I left, just realized that still love her 2 years later?

Do I want to be a guy who waltzes back into my ex's life and, realizing he had made a mistake leaving, decides that "now it's ok to steal a dude's girlfriend"?

I have never been like that. I was a very correct, polite, eager to please, and plan-following kind of person. I was selfless, and that was home. It's easy to please everybody when you're not in the picture. Problem avoidance wasn't hard, and doing "the right thing" and being honest at all times could keep me out of trouble for another 30 years, no doubt.

All of a sudden, I realize that I want to be happy, and that should be the priority. I can afford to be bold, and do and say things that are definitely shocking for anybody who had known me before "chapter 2", just because they're on the path of my happiness, and because I don't want to keep my feelings secret anymore. I can finally say "I love you" to Nemesis, and although this takes an effort on my account, I know it's true. It might screw her up that I say that, after all this time. She has never said it back to me...

I don't know if I'm becoming a nihilist, an objectivist, or a selfish asshole.
