Oh! 😅 Yes, you are right! There are some people out there who have both a lot of energy and a lot to say!
But please, keep in mind, this is not the kind of listening I am talking about here:
you have give expression or responds like "wow", "hmmn", "ehn ehn"... even when you are not listening.

What I like about this, though, is that you found your won way of dealing with her behaviour. You seem a very thoughtful boyfriend and I am sure you make her really happy.
All the best to you.
