Zach Bryan‘s ex-girlfriend Brianna LaPaglia is down in the dumps after being dumped by the musician in a very public way … but our “TMZ on TV” crew isn’t sharing her pain.

Zach’s statement announcing the split reads like she was way more into him than he was into her … at least that’s our takeaway here.
