I'm sorry that it didn't work between the two of you. Sending you a hug.
Allow yourself to wallow in it for a while; listen to Adele or whatever, eat chocolate, etc. Before – eventually, sometime in the future -- picking yourself up again.
I truly believe that the myth of "The One" is exactly that... a myth. Finding love is hard, believe me, I know... but not only are there other people out there that are right for you and you for them; but none of them will be 100% right for you, and vice versa. We all are human beings with many layers, needs, faults, and strengths. Simplistic fairy tale thinking will not help you.
And I know you're heartbroken right now, and that's ok. But once you're on solid ground again, maybe think about some of the "manipulative" things you did... and resolve to not act like that anymore in the future? Become a better version of yourself!
Now... break-ups are tragic and all, but let's talk about what really matters here: Congratulations for coming out to your parents! This is huge! I hope they took it well. This is so much more important than some boy (even a very nice one.) All the best moving forward!
