Ur bf is rare lately- Tu novio está raro últimamente (SPANISH - ENGLISH)!!

So, your boyfriend was unfaithful, and you realized it because of his constant nights out and his sudden, excessive displays of affection—since that wasn't his usual nature—and you could tell he was being attentive and thoughtful only out of fear that you would find out.

entonces,tu novio te engaña y lo notaste por sus constantes salidas y su amor excesivo y repentino,ya que él no era alguien así y pudiste notar que él era detallista y dedicado sólo por temer de que te enteres.
