There is lots of back story of course but I will try to keep it brief. I've posted in here before under a different name and had some great support and advice.
We've been together 7-8 years and have DC together. Our 3rd is due in a week! My MIL has often competed with me to be mother to our DC. Lots of passive/covert aggressive behaviour. Could bearly hide her disdain at us getting married. Says bitchy things behind my back, always pretends to me that she loves and adores me but actions are the opposite.
Recently DH and I had a big arguement about him not giving up smoking before this baby arrives. Massive bone of contention between us, and he ended up staying the night at his parents. After we had had a good talk and worked out a way forward (hypnotherapy and patches for the immediate future), he thanked his mum for putting him up and she made a big scene, started to scream at him that he couldn't change, he is who he is, what a wonderful MIL she is to me, said I was awful to her, he was stunned and furious with her. He is really trying to stop smoking and she is telling him he basically can't. This outburst came as he was leaving her house, coming back home to us.
MIL assumed it was all my fault why we argued in the first place and asked him several times 'what had I done?'. Am I right to think in some messed up way she would prefer to see us break up?
