It feels like I'm the one who was rejected. What kind of person is she?
Now it looks like I was the one who got dumped. What kind of weirdo is she?
この場合、次のように言うと良いかなと思います。
ーIt feels like I'm the one who was rejected. What kind of person is she?
「俺が振られたみたいやん。なんやあの女?」
振られるは to be rejected を使って表現できます。
ーNow it looks like I was the one who got dumped. What kind of weirdo is she?
「俺が振られたみたいに見えるやん。なんやあの変な女?」
to get dumped で振られるを表現することもできます。
