Would you still tell someone you liked them even if you sensed they didn't feel the same way?

@Poptartinvasion: thank you. I know, for years I would never say anything as vulnerability is a true fear. I also think that I missed out on pretty amazing opportunities in life because of that fear. I have realized through experiences that if feelings are that deep and powerful, they are worthy of being voiced. Come what may. It is more about me, expressing those feelings. Releasing them. Even though it is a risk, rather than basing my decision upon the reaction of that person. Which is truly unknown, until it is voiced. If feelings aren't mutual, at least the regret doesn't exist within- because I didn't try. I would rather receive a "no", than live with regret.
But, that is just me.
....sorry for my book here. Just trying to explain my thoughts.

@UnderOneSun: @ShadowBreath: Wasn't really looking for advise on this topic. Just wanted to get people's opinion and experiences on the matter. I've been in this situation before and one time I told the person how I felt and when the person rejected me, I felt like shit for months. Another time, I didn't tell a person how I felt and still regret it to this day. I've also been on the other side of this and had to tell someone that I didn't feel the same way they did which was difficult and awkward.

@LordofFlatbush: ...I, too have been on all sides, of that situation.
I understand.
