What do you think are the reasons kung bakit biglang naging cold and aloof sayo yung significant other niyo? Tapos kapag tinatanong nyo sila what's wrong sinasabi nila na wala naman? Do you think they're cheating/want to separate?

I agree with what everyone said. Madaming possible reason bakit sya cold, pero hindi naman agad ibig sabihin noon ay cheating sya or makikipaghiwalay na. If you asked him and ang sagot ay "wala", huwag mo nalang muna kulitin para hindi din makulitan at mainis. Bigyan mo muna ng space.
