Is AUTHOR wrong in the post ? POST : My ex recently broke up with me to “work on himself for us” and a week later had the married woman I asked him to stop talking to while we were together (because their relationship was inappropriate I’m not the only one who saw this) to which he agreed, staying at his place. 

I blocked him on everything because I can’t but would I be an asshole for embroidering his favorite sweatshirt with what I want to say to him (still thinking, will stop if I’m the asshole, but it can’t be too long a phrase anyways) before shipping it back to him. 

The only thing I think this will accomplish is some closure for me but if defacing clothes is too far I’d like to know. I wasn’t cheated on to my knowledge but still harshly heartbroken.
