grown feelings for fwb

I'm pretty sure I have grown feelings towards my fuck buddy and I haven't talked to him in a week and I'm pretty sure he's avoiding me but I know for a fact that I have not shown any feelings in front of him. i have a feeling a "friend" said something to him about me which triggered him to not talk to me. and I've tried to msg him to hook up or whatever but no reply. idk what to do it makes me feel sad and mad. :(
