What emotions and thoughts are arising as you begin to remove your ex from your mental and physical environment? I really don't have that much on hand to remind myself of her. The couple things I have I think are small enough to avoid or too big to get rid of and burn. Purging by fire can be cathartic, but seems wasteful when it comes to valuables, or art. Just sad really.
Create an "If this/then that" plan and put it in writing (detail what you're going to do it you're tempted to reach back out to her and how you will handle the temptation). This has been my long running strategy for these times, when I feel like texting or messaging, I instead write a pithy tweet, or take that photo I want to send her an instagram post. It works fairly well, and if it was not worth sharing with the world, it's not worth sending it to her. If I'm at home I do a household chore. Always plenty of those to distract. That's how I ended up volunteering at a history museum for the last nine years. My dishes are always clean. Heh.
Identify 2-3 new activities, hobbies, or pursuits you can begin to integrate into your life to occupy you as you begin the healing process and do ONE of them today. As mentioned previously, I've a pretty solid distraction process. I volunteered at the museum today, I've been there long enough that I've made it to the Association Board. Is that a good thing when you distraction becomes almost a second job? I'm going to pretend it is. I think I'm going to seriously teach myself to sew. It's a necessary skill, and I already have a base in it. Learning an instrument still seems beyond me. But I do have a harmonica calling me..
