I texted my buddy to express my confession, but there was no response. Will I not even be a buddy?

If you really love him, don't be afraid to let him know that you love him. Why water your love with cold water to keep it from burning? Since you have done it, you should have a vigorous love. Tell him that it will break the barrier between you, which is not a bad thing. If he really loves you, I think he will show it in his behavior even if he doesn't say it. If he treats you as a sister or a best friend, he will also hint at you.

The most important thing is to believe in yourself. If you don't say anything, maybe the only spark will be extinguished.

Take the initiative to play with him, take the initiative to talk to him, and he will think that you are the kindest person around him, or leave him on purpose, so that he will feel so empty without you around him. Believe in yourself, seize every opportunity, let him know your goodness, and let him know that he can't live without you.

Think about it, but do it, otherwise, all that remains is the faint fragrance in the residual petals of roses. I wish you success and hope you enjoy your love as soon as possible.
