Well done, but I don't agree with the message
It seems like this is an expression of something epitomized by the internet: "Cry moar emo kid". This is an expression in frivolous depression that stems not from actual hardship, but relationships. All that happens when relationships end is that. They end. It hurts, but you go on, because nothing horrific actually happened to you. If it was "True Love" as the saying goes, it wouldn't end, unless someone has extraneous circumstances. In this case it just seems to be an expression of loneliness, sudden attraction, the man does something insipid (Such as joking about suicide), loses the girls attraction, says he loves her, and she, behaving in the culturally trained female way, will respond by returning the affection.
This is why I'll never have a girlfriend that doesn't start to hate me after a few months. I don't accept that reality that they accept. Anyhow, interesting animation, and you tried your darnedest, it's just that it isn't anything new or important, or even interesting. I'm sorry.
