This question seems to be directed at the males on this forum, perhaps you would like the female perspective.
I assume here, correct me if I am wrong, that you are talking about how to treat your girlfriend. I think that most women, if you treated them "mean" as you put it, would soon get fed up with being treated like that and would find someone who treated them with respect. So you will put off the friendly genuine ladies that you meet by treating them badly.
Then you say about "not wanting to be taking advantage of". If you treat some one badly in the vain hope of keeping them interested, then you are taking advantage of them.
Is someone trying to get you to do things that you do not want to do?
You want to go out on your cycle in the Chain gangs, and she wants you to take her out somewhere? Just explain how important cycling is to you, and suggest a better time for taking her where she would like to go.
You also mention in another thread, that sometimes you feel "not right" - are the two connected in some way?
