Break up with bf


I broke up with my bf that I dont want to be with anymore, but I get upset or feel an urge even when I don’t want necessarily to know what he does(when I think consciously): my U model would be:

C: broke up with bf
T: ?????
F : urge to find out what he does
A: try to look for him without him knowing
R: not get things done (that I really care about)

I am trying to find out my underlying thought for U model, but I am not sure if I know why I have the urge.

In my Intentional model my thoughts would be,
‘My brain it’s keep repeating old habits’ and ‘I have false impression I still need to know what he does’
Or ‘I am learning to make conscious decisions about who I wanna care and invest my time in’

Thank you.
