Well, if you told him anonymously that you like him then that probably won’t do much unless you go off-anon and tell him it was you. ;u; I think the best way to approach this would first be to meet him off-anony.
Become his friend and build a foundation upon that and when you feel truly ready to express your feelings to him, do so knowing that now that he knows what a great person you are, that you can put your foot forward without any regrets.
And if you guys know each other already and you are friends, then try to tell him your feelings again when you are ready. Even if it’s hard I always think that these things are eventually gonna be something you will regret if you don’t speak up.
I know that before I used to truly regret not saying all these things to all these people and now I lost my chance. Who knows what would’ve happened if I had spoken up. ;u; So as hard as it might be, be brave. Push yourself forward. You don’t know what might happen if you do.
And if it doesn’t go exactly your way, still be super proud of yourself for putting yourself out there. It really is his loss at the end. ;u; Not yours.
