He's poking you. If he were serious, he would have suggested an alternative schedule. IM can ask him what changes he would like to make in the schedule and send that to you. Not the request to talk to you. He can ask BF to propose an alternative schedule ('BF, what changes in the schedule would you want to make? I'll forward the proposal to CB') and send you 'BF suggests to schedule every Sunday in odd weeks and Saturday in even weeks, would that be ok for you?'

Remember, only relevant and clean data should be passed. If IM keeps BF on a short leesh, he will stop asking personal contact sooner.
