Thank you for your question
My name is Clare
I shall do my best to help you but I need some further information first
Which part of the UK are you in?
Is her doctor aware of the problems
Do not worry about that at the moment.
Are you ready to end your relationship?
So how do you intend to move matters forward if she will not leave the property?
You cannot force your wife to leave the property unless she is violent towards you or the child.
You certainly have sufficient evidence that if you decided to move out with the child you may well be able to obtain a Court Order stating that the child lives with
you - and has contact with mum in a safe environment.
Another alternative is to make arrangements for your child as if you were indeed a single parent - ensuring that your wife is never alone with the child and to make it clear that this will continue until she has had the help that she clearly needs.
If she makes the situation within the home untenable then you may be able to obtain an Order excluding her for the good of the child
I hope that this is of assistance - please ask if you need further details
