Money's too tight to mention!

Hi
New to this so here goes! Have been considering divorce for some years now. I don't know if my circumstances are unusual but we jointly own the marital home (with no mortgage) and my husband gives me such a small amount for housekeeping that I now find I am living in debt on my credit card. I have an 8 year old son. My husband pays me £400 per month (he has no outgoings apart from this £400). I have a part time job that brings me £700 per month so I am trying to run a large detached house on £1100 per month. I have to pay for everything and I mean everything from my son's football practice costs to childcare during the school hols which ain't cheap. Food, council tax, utility bills etc. My husband simply will not pay be one penny more and I feel my only option is to file for divorce before my debt becomes much more of a burden. In my husband's eyes, the fact that he sees me with a glass of wine at the weekends leads him to believe that "if you can afford wine ...." but that's not the case. I never go out because I can't afford a babysitter (which I would have to pay for before you ask) and that bottle of wine (always ones on special offer) is my only luxury. I rarely go out with my husband and recently he insisted that I would have to pay for my own drinks. I'm in a desperate situation.
I can't be the only one can I?

Has he always been this miserly?

Why are you paying council tax and utilities? Aren't they also in his name? Why buy your husband food or do his washing?

You might want to point out to him that divorce is potentially very expensive.

No he hasn't always been like this but things changed when we had our first child and I lost my very lucrative job when I asked if I could go part time but that's another story!

Everything is in my name. I wonder if they would put it in joint names if I just asked them to or whether he would have to get involved, in which case, it would be a problem! I try to keep the peace for the sake of my son but it isn't easy. Ideally I would like to move out with my son and just leave him to pay all the bills and I am currently trying to find a lowcost solution so that I can try to keep my son away from any heated situations.
