Our old neighbours brother confided in me at a party, never met him before, and he must have had a few to drink, that he and his wife had split up, but continued to live in the same house, as neither could afford to move out.
They agreed this. His wife got a boyfriend who moved in, and he was OK with it, as he soon got a younger girlfriend ( he mentioned this point)
But the guy, told me, he wasn’t happy, and wanted to get back with his wife, as it wasn’t the same with his girlfriend.
He was upset it was all one big mess.
I’m not sure if they had children, I have no idea whatever happened.
Best of luck, but I imagine it would be very difficult, and I’ve read many times, that the splitting up part is a very dangerous time for women, as you never know how they’ll react.
