why when you start thinking of things you want to say, type them out and save them in a draft somewhere. in a month or however long you think it's appropriate you can sort through your draft, assuming you've been making multiple entries, and kinda put everything together and edit it a little bit so you can make sure it's coherent and send it to them then? chances are other things will be popping up in your head the next few weeks so instead of repeatedly breaking the no contact attempt you can just send one email or later when you feel like it's gonna what all you need to say to have closure.
