You have asked him to come to some resolution about finances and less than 24 hours later he sent you this message. You told him you would prefer to have a professional help you sort out the finances so he has provided the necessary information for you to do that (pension statements). If you isolate the finance issue he has followed through with what you requested.
Opinions will differ but I firmly believe if a spouse walks away the burden of filing and paying for a divorce is up to them. If you don't want to get divorced then don't make any moves other than sitting tight, working on your finances and DB'ing. If you are served then reply according to the law but don't offer an assistance with the divorce. I am not suggesting to make things ugly but there is no reason for you to do anything more than what you are doing.
