Hi Tifa, if you look at why you're forgetful, as in the values that are enforcing that behaviour, then you will have to ask if that's a value Williams is adopting/changing to as well. He may just be adopting a different "behaviour", which is fine, because his values may still remain the same. He's adapting to you also meant he love you, of course.

Mindfulness, which helps forgetfulness among other things, is a good habit to have, regardless if you are single or in a relationship. Perhaps look for apps to help too?
