MIL messages me to tell me to tell DH she has sent him a message on FB Messenger. This gets right up my nose, for reasons I'm not sure I can explain. Is this something I really shouldn't be irritated by? Background: DH loves MIL but is not great at keeping in contact with his family- finds them all fairly over-talkative and over dramatic. MIL has v poor credit and thus can't get a phone contract, so calling DH is difficult for her... not that he usually answers when she does, as he just doesn't feel up to her.
