Is he valid for breaking up with her?

Some may think he overreacted. But finding someone who respects your aspirations is so important.

Should straight men be allowed at lesbian bars?

Willing to bet it was the last straw, and she habitually disrupted his efforts for her own amusement.

She deserves to be single for the rest of here life

Honestly, if she knows how much he cared about that cup tower, maybe it’s not about the cups, but more about respecting each other’s efforts. He might be justified in feeling upset.

Very valid. This is little, yes, but what someone can do in little things shows what they can do in other significant things. She doesn't care his hard work, the time spent and whatever it is he was doing it for. She will do the same in other "significant" things.

Breakup? I'll do this

This was intentional, bro made the right choice 👏🏻

She just wasted all his Time and Effort, and she laughing.

There have been lots of things like this before. You can see it in his face.

I would only assume she's messed with him in past projects, so yes, valid.
