Always had an issue with mil. She is a spoilt only child who has pushed all her shit onto my oh all his life and is a master of manipulation. My oh has one younger brother who has got away scott free.
My bil is now married and his wife is just like my mil - spoilt and vile. Both my mil and sil gang up on me and have ruined precious moments for me and my oh. - ruined our wedding planning, ruined our pregnancy by being bitches over it (i got pregnant 2 months prior to sil and my mil wanted her to have the 1st child, sil felt the same and ignored our pregnancy!).
My oh and i do nothing but argue over his mother and our sil behaviour. They are very sneaky and because its always 2 against 1 it always looks like i am the badguy despite it being plainly obvious by what they are doing that it is them.
My oh keeps threatening to leave me (i am pregnant!) because i cant get on with them. I have tried and tried but even mother theresa wouldnt stand a chance. The bottom line is that his mother hates that she is no longer his world and cant dump her shit on him anymore, owing to me and his child being around (a gc who she makes no effort with compared to his sil child - with the exception of big events like xmas where she rolls in and expects to be treated like a visiting queen)
Im sick of arguing with my oh. He does understand that its them but he is very frustrated and angry that his relationship with his mother has turned sour as he has noone else except his brother who he has never been close to (her fucking fault for being a mind-fucked bitch that constantly bats them off against each other and has favourites tbf)
Really dont know what to do. If i leave then part of me thinks they will hold a celebration and welcome my oh with open arms blaming me for everything as its an easy option. The reality though is that I have told my oh that if he threatens to leave me again i will pack his bags for him because nothing will change - his mum will always be a bitch and so will sil, regardless of who he is with.
I deserve a husband who puts me and our children first and who can see the warped nasty behaviour of mil and sil for what it is.
How can i make this situation better? I dont want my inlaws to drive an even deeper wedge between oh and i but they are doing a very good job!!!! I feel helpless
