being the good / nice guy

I wonder if I really am a Mr good guy.
I thought I was a Mr good guy, because I usually help people if they want me to help, and is nice to almost everyone, and don't mind being hit (whatever). So maybe I fulfill the qualities of a Mr good guy.
Apart from that, maybe I'm too nice, such that I became easily used. Someone had said that everyone knows that I was used since the start of the year for certain things. Decide not to reveal these since 'everyone knows', and I don't really want to spoil a friendship.
Ok, maybe I know that I'm being used. Maybe I don't know. I don't really care. I think it would be better that we just stay that way, because I'm happy. Because I'm super dense, and I don't give up. So maybe I never realise how stupid I was, but I still don't, and I don't want to realise that. Sometimes it is good to be ignorant.
If you don't get what I'm talking about, nvm..occasional randomness here. Just that I don't mind being used, but don't hurt me, and treat me nicely.
