Is it so bad being a good guy?

People say that I'm too nice That's why I don't have a girlfriend, that's why I get stomped on by my colleagues.

My girl friends say that I am too nice to be a boyfriend. I am husband material not a boyfriend material, because I'm too nice Now I don't go lie down in front of people to serve them, I do little things in courtesy.

Is it really a bad thing to be a good person? To wait for other person's food to arrive and then start eating together? To give everyone respect and talk nicely? To treat everyone with basic dignity? To wait for someone for a minute so I get to talk to them while going for our separate classes? To love everyone and everything irrespective of anything?

I feel some people take me for granted and does not respect me. They invite me for the sake of it, but if I am not present they are not affected. This further adds to me being a little uncomfortable with them, have low confidence, and feel bad about myself. (Ik this is not completely true but still I feel bad whike being with those people)

(You'll say to just leave thode people, but they are my childhood friends. We grew apart. They all are much closer and I got a little away from them. I would really like being appreciated and respected but I don't see that happenning)
