The reality of what your ex's are doing this weekend probably doesn't match up with how you are anticipating it.
Realistically, they may have moments of when they are feeling ok, but you know there will be some drama or misery that they are engulfed in, and relay upon the others around them. Is that something your really want to be a part of still?
By focusing on what they are doing, and setting your expectation of the weekend to be horrible for you, what good is this doing for you?
We talk a lot about self-soothing on Personal Inventory, and what things you can do to soothe yourself when you are feeling low. What are some things you can do that will make you feel good this weekend? How about focusing on that?
You let them control your head because there is not enough distraction to replace it, and we just need a little to keep it through the day and therefore slightly heal through the process.
Unfortunately i still have the flu, so watching/reading stuff on the laptop in bed and do a little game here or there on a tablet. Haven't heard sh!t from the family what they do in regards of easter and i aint anticipating any calls from them either. Only 'happy easter' I got ... is ... yeah ... from my BPD ex.
