Definitely sounds odd to me ....would investigate the gambling theory ...having been married to a compulsive gambler some years ago, this sounds familiar ! His employer suggested he join GA which he did, but as with any addiction, unless it is the addict who wishes to join, it will have no effect ! Like you D I paid all the bills and the mortgage as he had stopped doing so .....our daughter was in a little private school that I paid for ....I bought all the furniture etc for our new house ......only given money when he had a win on the horses. Terrible time ! He then left me for the local barmaid and I sold the house (Long story, but made sure I got the lot, house and contents)....after I bought another house outright and moved hundreds of miles away, I had a call from his new woman one day in tears asking me why I hadn't told her he was a gambler ! ...now why would i do that !
Companies House is a good idea ....gives you details of all directors of a company balance sheets, profit, loss, money in bank, etc and when last accounts filed ....I use this to locate my daughter ...like you , I paid for my D to go to Uni for four years, bought her a car, paid for holidays, flights out to see me when I moved to Spain, paid her rent and an allowance every month ....even offered to buy her a small house when I sold mine ......however, when I became an OAP and she had a very good job I said sorry, cannot do much for you financially anymore ....final crunch was when she e mailed 10 years ago to say she and her then boyfriend were coming on holiday to France (where I live now) and bringing his two small children ......I said ah lovely ! you can come and stay and I will pick you up from the airport ! planned all the things we could do, beach, activities etc .....no word from her. Tried to contact her for dates et ,,,,no answer ,,,,struck me off contact with all her social media sites ....no word ever since May 2008 .....which leads me to the only conclusion that she expected me to say,as I usually did, that I would pay for everything ! SO ...if you don't mind losing all contact with your D and the GC's ...tread carefully ! My D (discovered via Companies HOuse online) is now apparently living in a large house (looked at that online too...Zoopla) with someone else and there is a photo of a child aged about 6 or 7 could be hers, could be his, no idea !...looked him up too ...Companies HOuse as well .....so at least I know where she is and just hope she is happy !!! All I do know is that if, when I get infirm and need care, after my house is taken by the authorities to pay for it they will pursue her once the money is gone !!!! I WOULD hire a private investigator if only to put your mind at rest ...AND I would pay no more money ..but you could suggest to your DH that you put money aside in a seperate account to help if disaster strikes for your daughter o GC's, without your D knowing That way you would then be able to help, but she must not know about the account unless necessary once the sponger leaves !! 
do you still buy BBC radio times?
What did you you think you would have by your current age that you don't?
