I have read many many times that to keep plates you are supposed to keep the righ attitude and dont indulge in "boyfriend behaviour".

Thera are a myriad of posts on the former, but after some thinking I don't quite have a clear picture of what the latter means. I understand clingy behaviour and being overly invested with the girl is considered boyfriend behaviour, but I'm talking about the finer things.

For example, going out for drinks is not considered BB, as it is a good starting point for a joint activity, and perhaps the stereotypical "I'm going shopping, do you want to join me?" date from PUAs if it doesn't become a regular thing; but how about going to the movies? or for a walk? or inviting her to a weekend event?

I know the best way to find out would be to calibrate IRL but I have other priorities at the moment to spend too much time on this. Thanks in advance.
