@RobbieGoodwin Interesting! So it sounds like 'relate to', with my intended meaning, came first, and it's even dubious as to whether I can use 'relate with' interchangeably.

But to my American ears, it sounds very natural to say that you relate with something when you can either sympathize or empathize. More @Wikipedia
