can't get past; can't get over itUsed literally for being unable to pass through a place, and figuratively for being unable to let go of something or for deliberately making things difficult for someone, as in 跟某人过不去.
CH: 这件事已经过去很久了,你就别跟自己过不去了。
EN: This happened a long time ago, so don't keep beating yourself up over it.
