Hi, thank you for your question. You are able to pursue a divorce in England or Wales so long as you remain resident here. You can do this under 5 year separation and do not require her consent to do this - you can see the process for divorce, along with the relevant forms here: https://www.gov.uk/divorce/overview
In relation to the proceeds of sale from the former matrimonial home, this will be more complicated. She does have an interest in the home arising out of the marriage and it is unlikely the funds will be released without this settling and a court order is made. If you can still no longer contact her to voluntarily agree this you will need to apply to court for financial relief and a court will make a decision as to what is a reasonable way forward - you can pursue this using Form A and a £255 court fee.
I hope this assists you. If you found this information helpful please provide a positive rating using the stars at the top of this page. I will not be credited for your question without a positive rating. Thank you
