Yes all this advise is true. Good manners I feel is the most important. Be on time, hold open the door, call if you say you are going to...etc. I think this is respect in the highest degree. Be honest, if she is not for you, tell her, don't leave her hanging.
Personally I would like to be treated like a human being. Treat women like you want to be treated and you should be fine.
Music I use to see this guy who treated me like a queen with I was with him it was when I wasn't that there was a problem. Seemed to forget I was alive, 13 years later he treats his daughter the sameway.
