No. I don't think so. My motto in life is be selfish. Your happiness and your regrets are all your own. "Blurting out your feelings" was more than the correct response. Take chances at happiness, my friend, even if it might cause discomfort to others. We all chalk it up to experience. Don't hate yourself. Just look back at the fuzzy feelings you had as fond memories and look forward to next time. (● ̄(エ) ̄●)

I was used to be in love with another girl, I did confess to her that I saw her more than a friend and I would be okay even if she rejected me.
She told me she loved me too but we couldn't be an item, because we both are girls.
After that lukewarm response, I tried to keep our distance because I didn't want to bother her life furthermore (especially, to protect my own feelings), but she kept sticking to me, telling that she loves me, I was her most special person on her life, and it got my hopes too high.
One day we met on an anime-con..... But shockingly, she brought along her new boyfriend and introduced us. I tried to look happy for them even though I really was in shock until I couldn't hold back my tears at public bus on my way home. (well, gratefully I could face the window so nobody else notice a random fully grown young woman cried because she had her heart broken lol).
Few years has passed and now I am no longer in touch with her. When I rethink about it, I really was the selfish one for blurting my feelings out and making her confused. I tried to move on, but this self-hatred is inevitable.
