My daughter is 18 and her boyfriend is at our house a lot, they are nearly inseparable. We have found on several occasions that significant sums of cash have been stolen from my husband's wallet and we have gone from making other excuses to explain this, to that we are now of the firm opinion that the boyfriend must be the culprit. We confronted daughter with the facts that money had gone, and had she taken it?- she swears not- the indirect implication to her was of course that he had taken it. What should we do next please? I am now very uncomfortable having him the house as I don't know what else he might be capable of.
