Ako ba yung may problema?

Problem/Goal: I can feel my suitor is losing interest in me.

Context: Problem just found out my suitor has slept with his best friend (f) tho they act and treat each other as siblings, I can't help but to overthink. Although nag paalam naman yung suitor ko na doon matutulog sa kanila yung bestfriend niya kasi matagal sila hindi nagkita, I appreciate the honesty, pero I still find it insensitive knowing na he's into me.

He didn't fail to update din during her stay, but prior this, I can feel that he's somehow off.

Ewan, is it just my thoughts feeding me doubts? Then I acted cold, and his response was 'He needs time alone'
