What are some songs that relate to this?

I was talkin to this kid for 2 months, I really liked him. Everyone said him & this girl were together but I was confused cause his fb said single & so did hers. In school they acted like they didnt know eachother. I asked him and he said they werent together. I never put myself out there. & I respect myself. But I made a mistake, we hooked up. Next thing you know his fb 2 days later says “in a relationship” everyone said they had been together they just never made it “fb official” basically he screwed me over..do you know any songs that kind of relate to this?
