Still struggling six months later

As the title suggests. I thought I was moving in late last year but I’m still struggling six months post discard.

I’m trying to do everything right to get past it all; routine, therapy, exercise, etc. But the rumination won’t stop.

I think the hardest part is knowing she’s still with the new guy. I can’t even fathom how it’s still lasted and makes me wonder what I did to force the discard.
