It would leave your ex in a really shitt Y position.
I can't do this any more. I'm miserable.
But my partner moved here to be with me. If we split it means no house, no money. We have no savings so no way to immediately set up an apartment. No family support for my partner.
Basically I would be throwing them under the bus.
But I'm so unhappy.
I don't kbow what to do.
