Can’t stop crying

I’m sitting in the bathroom balling my eyes out I’m so sick and tired of this guy. I put so much energy and effort into him but lately he hasn’t shown anything back and tonight he just left with no txt , call nothing he disappeared on me and I feel like he’s talking to somebody else now he used to let me know his whereabouts not bc I asked him cs I never did but he voluntarily did it for so long now he never does it kills me that something is different about him that maybe he’s moved on behind my back.

Idk what to do anymore and I think I’m just going to block and move on. He probably wouldn’t even care if I disappeared with no explanation anyways. Iv explained myself way too many times for him not to know what’s going on he just doesn’t care like he used to.
