Fwb, feelings.

Hello, I got a new fwb like two months ago at first I told him I wanted there to be vibes and we can talk to each other not just hook up & leave, I wanted something more sure. Fast forward two months in & he just likes to hangout for the hook up but we never hangout anymore to just vibe, my feelings are hurt cause something tells me there’s other girls & if I didn’t want to hook up he wouldnt talk to me. I want to cut it off but I feel like I should tell him how I’m feeling, my friend says he doesn’t deserve an explanation to just cut him off. What do you girls think??
