Basically as above.
I am on mat leave. We have not been getting on for a long time. He is full time employed, so am I. We have agreed to part but he will stay here until he can find somewhere else. He has no family to live with. Will I be eligible for any form of benefit whilst he is still under this roof? Finances are not split and he will need his funds to relocate. He will contribute to the children and the household.
