Am I wrong for feeling this way?

i dont think you're wrong at all for feeling that way. if that happened to me, i don't think i could even think about a new girlfriend/boyfriend if i was that in love with her. i think he's using that guy as a "rebound" if hes only known him for two months to forget about Elania. and thats wrong to act like shes never exsisted. he's being somewhat selfish.
