No, that's just not possible. If indeed he is a genuine guy, a true gentleman then it's not possible that he will ever manipulate you. However yes there are people who act, who show off, who fake in order to make someone like them, there are people who do all that.
In that case if a guy was pretending to be like a gentleman then yes he can be manipulative.
"Only if he is showing off/pretending", otherwise not.

Yes a guy can do that. My ex told me how great of a guy he was (should have been a red flag) and at 1st he was wonderful (at least in my eyes), come to find out it was an act. You can only find out by spending a lot of time w him. Of course at the beginning its easy to keep the ruse, but no sustainable in the long run.
