Simp

Due to a broken heart they've developed a cold heart. They cry often and often feel trapped. They became coldhearted because they realized that the person they messed with heavy didn't even care if they lived. They're so blind by love That they usually don't notice their partners flaws Yes! they're sometimes "possessed" by their relationship, but they don't have any compassion for their partner and often feel abandoned and misunderstood.

He doesn't even notice that she's using him, he's such a Simp.
