OK, so I guess everyone has a type/preference/whatever lookswise, but...

has anyone ever dated someone who literally looked exactly like someone else? Or dated someone who has an ex that looks a lot like them?

I'm currently getting very positive signals from someone who really is the spit image of someone I had a serious (unrequited) crush on a couple of years back, and it's weirding me out a bit.

I would take either of these

both @ the same time high fiving over your back

lol
you know it. i'd take their quarterback juice any day

By "positive signals" I assume you mean facial scabs and hollow eye sockets. Any other meaning would clearly be a misunderstanding on your part.

Just don't let this one leave you felching out his load at the alter while he's on the first plane out of the country, again, lol.
