Worried about the past?

If your husband never saw or experienced any physical abuse, then it is likely that the father mellowed with age or the abuse claims are overstated. Regardless, if your husband isn't the least bit concerned, you probably shouldn't be either. Neither you or your husband have ever seen an issue. Maybe you should talk to a doctor and/or therapist about your anxiety disorder and tendency to fixate on things. The relationship is good, their behavior from everything you and your husband have seen is fine...yet you are worrying about something that may have happened 30something years ago. That isn't a good way to go through life.
