I'm the same as 3bm - I only initiate if it is about S13 or something really important that H needs to know, otherwise I have let him initiate all contact. Most has been by text, although today he called about something he could have easily texted. We do go days with no contact, but H has lately been contacting me a bit more, as well as coming round to the house more often.
I found it much easier to detach after he moved out. It was really difficult at first, but does get easier.
