Blaine hated lying.
His conscience couldn't stand it half the time. When he was 4 he used to run crying to his mother in the middle of the night, constantly apologizing for telling her he took 2 cookies when he took 5.
And now here he was a 17 year old lying since the age of 14 about who he was, what he was. But now he couldn't go running into his parents arms and tell them everything. Blaine was as good as dead to them now, unknown to them of course.

He could never be that brave,
they had been fighting people like him their whole lives and now he was the exact thing they hated.
Blaine at least accepted himself for what he was now, a few years before hand it had been a different story.
First it was the lack of girlfriends, there were always plenty of takers but Blaine never felt anything.
Then he watched 'those movies' full of beautiful women and good views of as he now classed them 'lady parts'. Let's just say that didn't go to well for him considering all that seemed to rise was jealousy in his throat. Jealous of Misty Martin and how lucky she was to have that pool cleaner guy,
that's when things started to turn bad.
Walking through school he found himself absentmindedly staring at other dudes and being constantly terrified someone would catch him.
Blaine stopped talking to his friend's hell, he stopped talking to everybody, his grades were slipping and when he did speak it was always in an extremely rude and witty manner.
This went on for nearly a year until the school Dean and his father gave him a firm talking to that had pushed him harshly back to reality.
Why did he have to be gay? Why not some other random kid with accepting parents? It shouldn't have been him, the son of a political leader who is adamant on putting an end to gay rights.
Blaine was almost adamant he would die lonely or be unhappy in a marriage with a woman. Honestly Blaine would rather do that then 'come out' to his parent

So here he was Blaine Anderson born 4th of May 1994,
living a lie.
