what is wrong trying to be a good guy?

I think you should continue to be a good guy. I don't mean let people take advantage of you, but if you continue to be the good person you are, you will be rewarded for it. Often I feel like it is not worth it to be so nice. I wonder why do I bother? But it makes us better people, and if other people want to be hurtful or disrespectful, that reflects badly on them. I don't want there to ever be a question of my own character.

If you feel someone simply deserve all your effort and time that you put into being nice for them, don't do it or do it less often. Also, it is NEVER selfish to ask someone to treat you nicely. Tell them that you never have been nice just for something in return, but that the least they can do is be nice to you and at least think of their actions and how they might affect you. If things remain the same, you see that the person simply does not value you nor your affection. These people are leeches, and so, you should try to stay away from them. It is never selfish to want yourself to be happy if you always spend time and put in the effort to bring a smile unto others' faces. Just remember to be as polite as possible when talking though! Good luck!

when you want to be a good person and they dont deserve you i think you mustn't negative thinking because every people need time to accept you good habits and if they're not deserve you just accept it,it's a experience that you can learn how to be passion in life
