Tell them…every chance you can. Why do people think its better to leave doubt.telling someone you love them and showing it never killed anyone. It also never made the feeling of love develop where it doesnt exist already just because youve said it right? So why do people have such a time with saying it when its your truth. Keeping it to youtself doesny stop you from feeling it right? If the person leaves because they never knew about you loving them, ot doesnt make you hurt any less, right? So say so..let them know!
