Do you know the story about the cold turd?
Soon enough, you forget it's a turd and you taste it again thinking it's chocolate. Then you remember that it was a turd in the first place. The other guy, you never broke up with. I would pick this one.

Hmm, there's a saying: if you love two people - pick the second one. If you truly loved the first one, you wouldn't have fallen for the second one.
However, in this case, I'd pick the first guy. He offers stability, God knows what the other guy can turn out to be. I wouldn't sacrifice all that time and memories shared with the first person.
