Obviously we all know the fun bits of going from idealizing your relationship, to devaluing it, but lately I find myself wondering if I'm really devaluing it, or if how I'm feeling kind of makes sense. 

E.I, my ex best friend works with my partner, 
(long story short she lied to, &amp; about us, shit on my partner, &amp; myself, &amp; I ended the friendship after finding out, super long story) 
&amp; I made it known to my partner that a lot of my feelings were still fresh, and I didn't wanna hear about her, &amp; I made it known it bothers me that he's buddy buddy with her after all of the bullshit but i understand they work together. I made it known that i would be taking extreme distance from her and if my partner heavily associated with her i would take distance as well for my own sake. Basically just keep the bitch out of my life, and out of my ears because it upsets me. Simple. 

Fast forward to today (literally the next day) &amp; my partner thought it would be a good idea to send me a video of a cool scenic view with her in it, he's talking to her during the whole video, and ends it by panning to her and saying "say cheese *name*!!"

I asked him to leave me alone for a few days after that. Especially because his reaction was along the lines of "sorry i don't spend all of my time thinking about other peoples feelings" &amp; "don't you get tired of being mad and frustrated with everyone all of the time i know i get tired being on the receiving end" after he just told me he would be mindful that i want her out of my life. not one "Sorry you literally just told me how you felt last night and then i just shoved it in your face twelve hours later my bad i wasn't thinking"

My partner and I live together, &amp; I was already in a bad state when he left for this 10 day trip with his sales team, &amp; I guess consideration of the fact that I'm not doing too well, just getting into treatment, &amp; need a little more effort/care would be nice. Wish I didn't have handfuls of examples like this.
