If something is going on a mistake will happen soon. I simply let ALL the info come to me, never asked any questions to anybody and actually kept all this to myself for five months.
Do you and your H share a family cell plan? If so log on to the account and see if your carrier keeps a running log of all calls made and received. You won't see names but you will see numbers/times/dates/length of call and so on. I know both AT&T and Verizon wireless have this feature.
