So I had a brief chat with a lawyer today (five minutes on the phone). I really appreciated her giving me her time...I know how valuable that it.
Anyway, I don't think I'm going to be able to have a legal separation drawn up, as I can't afford it. That was an avenue I was possibly going to explore, as a boundary for myself.
The good news is that she gave me some advice on my house, and the little money I have. House is mine, it's not matrimonial property. Money is also mine.
H would have to put in a claim for compensation for the money he has paid towards the mortgage, but I could counterclaim for his pension.
So I've gathered some more information, but I'm doing nothing about it for the moment The status quo will continue for a while longer, while I carry on with living my life and working on myself, whilst also taking the time to slowly think things over. Perhaps something will change at some point? I don't know.
