Oh - and about MIL coming to help you - please make sure she knows what is going on before she comes. Be brutally honest. H is living with an affair partner, the woman spied on you and threatened suicide, she doesn't want him seeing his son etc. If she can't be on your side you don't need her there. And honestly, you don't need her there if she's going t be there telling YOU what YOU should be doing to "win him back". If she can't see her son is totally being a cad, you won't want her there.
