What would you tell your daughter who is intent on marrying a man who has been unemployed for about 10 years?

Supposing he was a nice person, well over 40 years old. Someone whose business failed just over 10 years ago. Since then nothing much has happened in the person’s professional life. Financial help has been coming from the person’s retired father, borrowing from friends and girlfriend and doing odd jobs to help out family and friends. There is no plan for future pension. A kind, helpful person, but seems to have no sense of responsibility, especially when he states his desire to get married and have children despite the on-going situation! He vehemently supports that love, support and companionship are what really counts!!!!! Would you happily wish your daughter the best and let her jump into boiling water, since she would be the one basically supporting the both of them?
