yes, it gets easier. in my aftermath i didnt want to use foam soap (first used it at her place) or even run hot vs cold water cause she claimed i was really good at finding the right temperature for her bath (thoughts along the lines of how can she even run a bath without thinking about me?).
there are two schools of thought on this and both are right. one is to dive into these things; go to the places that trigger you, do the things that trigger you, use the objects that trigger you, eliminate the emotional negative association by exposure. the other is avoid them for a while, avoid triggering in general, until youve had some time, and then to slowly approach them.
balance between the two is a good idea. you no doubt carry associations large and small. it stands to reason that the smaller ones will fade more quickly. larger ones, like holidays and anniversaries, special places or things you did together, will take longer.
time will heal a lot of the wounds, exposure over time will heal others. its a matter of balance and it relates to
your personal recovery/experience. take it as
you feel youre ready, associations large and small
