For those of you who struggle with still receiving emails from exes, what email program do you use? For me, I use Gmail which is free webmail provided by Google. But in many cases I think the same thing applies whichever email you use.
All you have to do is go to your mail settings and create a filter that applies to the exes email address, their full name or whatever. I've used this method when I was really struggling with the idea I would receive something from him. I went to pieces with any message or missed IM, it was doing my head in and crashing into my day ruining it whenever he contacted me, my heart would thump so hard my torso jolted, I felt sick, shaky, scared... so I used a filter to 'funnel' any messages from him into a named folder, bypassing the inbox. Doing so gave me back control over the situation, and stopped the heart in mouth lurching whenever I saw that I had any new mail - because I KNEW it wouldn't be him. If I got a message from him, it would show in the sidebar that there was something new in the folder I'd created with his name where all emails from him were redirected. Then I knew without even seeing the subject that he'd messaged, I could take some deep breaths, give myself a pep talk and then read it, if I chose.
I mean, after all, why should they infiltrate our email they way they've infiltrated our heads and hearts? Don't give these men that privilege, keep them in their own separate space so the rest of your life (or email) isn't soiled with their silly messages. It cuts down on the urge to reply, too. Perhaps because it makes clear that they are a different case with different rules, and do not deserve or need the normal courtesy of a swift email response.
The stronger among you may just want to divert all messages from exes straight to the trash
