Losing interest in general in the other person. Don't have that "mushy" feeling for them inside anymore. Not worried about what they are doing, how long they are gone. Instead of feeling anxious to see them, rather you wish they take longer to get home. Not in a rush to see them anymore. Not thinking about them so much. Not considerate of their feelings as much as you used to be. Putting other people/things before them. Your heart will always tell you if you are in love or not. You just need to listen. I hope this helps, and good luck.
My partner said that she no longer feel obsessed about me anymore and that the lust is no longer existent
