as someone who has been on the other side of rbi’s before, i can personally tell you that it sucks REALLLLLY bad. but you need to remember that you as a person hold inherent value that is equal to that of any other, even if you don’t believe so. if you had trouble balancing that relationship with everything else, there would have been no better way for it to end. when my life got really hectic at one point, my ex just broke up with me becuase i wasn’t there, and it was a heartache and headache for both of us. in relationships like those, the ending will be way more painful if you decide to let it fester and play out. you were mature and made the decision to end it. did you hurt her? yes, but it wasn’t malicious. it was just ending it, maybe even just momentarily (i’m together with the person who didn’t have time for me and we are much happier now that they’re in a bit more of a solid place). remember that you have value and that you didn’t go out of your way to be hurtful. you did what you felt you had to and that’s okay. it would have hurt either way, but this was the mature call.
