by the way he or she looks at you and the way he speak to you
Tell them that you have feelings for them or have a friend tell them u hav feelings for them
Just tell them. They will understand your feelings.
"sorry, i like someone else" sincerely.
tell your feelings to her/his friend and let her/him tell to the one you like!
well if you don't have feelings for that person anymore and that person doesn't have feelings for you anymore i think it is safe to tell them you had feelings for someone else .
tell him ur feelings and be allways there for them
Tell him the truth
You have to tell them even if you are too shy or scared. If you really want them you will eventually have to ask. :)
It is hard to tell. Just tell that special someone about your feelings and they will let you know.
tell em how your feelings and if it not to be, then it's not to be.
RUN
If they are very flirty and if you text and hearts get sent outt
