Now that I have made myself familiar to the news of dating coaches like Mathew Hussey and Elliot Scott (on YouTube, if you wanna watch!) I can say this is really relevant to me - but no, as well to your girlfriend. 

Girlfriends want to make sure that you have an interest in their feelings and relationship. If you're looking up dating advice, it'll make them really think you care. 

Also, it'll make your girlfriend feel particularly great if you acted upon that advice. Think about your girlfriend for once. Really have questions. 

What does she want? What does she hate? Why is she acting like a clingy idiot? Why does she talk so much? Why is she so wonderful to be around and do you show her enough attention? (Read books like this one. You'll be a step ahead of the game.)
