Please know that I am thinking of you - you have been through a tremendous amount of stress recently - when you say BIL did it - are you talking about suicide? Please tell me I am wrong. If your H was not over the edge before, if suicide is the case, then he will be now and I know this will affect you negatively as well. There are no right words to say - I can only offer condolences and love to you and your family (including you beloved dog) - may God bless you all.
