namechanged, sorry. if you recognize me, please don't say so...
i'm pregnant with what will be the first grandchild for my MIL. we live abroad.
i'm not going to go into the massive backstory, but suffice it to say MIL is manipulative and controlling. she once had a veneer of loving care, but ever since we moved, she has been sticking the knife in.
it's quite clear to me that she is furious that we upped sticks without her "blessing", but neither DH nor I are the types in involve our parents in our lives at that level. it's nothing personal, but it is very clear that she has taken it personally.
her biggest gripe has been that we don't contact her enough. her solution: ensure that every contact with us includes at least one passive-aggressive gibe, sometimes quite nasty stuff really, re: religion, finances... REALLY personal and cutting stuff, and all tied up with the massive backstory i reference above.
this led DH to limit contact with them. which led to MIL playing the martyr more and more. which led to DH limiting contact even more... and so it has carried on.
my DH is NOT someone to pander to emotional games and has utter nerves of steel with this sort of thing. DH will NEVER allow her the influence she wishes to have over our child, and she is going to spit her dummy out ad infinitum in the belief that doing so will change his mind.
but it won't... she raised her son, how can she not know that this is not the way to approach him?? i feel quite sorry for MIL... she is playing a game that she should be able to see she will lose... 
so now, DH has mailed to tell her we are expecting. (he has told me point blank he won't tell her via webcam etc. because he won't have her ruining a happy occasion with a cutting remark.)
and as i predicted to him, she frantically messaging me, trying to get ME to press-gang her son into Skyping her immediately. i fucking hate this. all i want is for this to be a happy occasion and instead we have to "manage" MIL.
i showed DH the messages and he is currently downstairs composing email to explain frankly to her exactly why he is not going to skype (gulp... i am not like DH! the thought of the fireworks that will ensue frankly terrify me) and why she needs to leave me alone and be respectful of us.
someone tell me i am doing the right thing by maintaining my distance/not replying to messages, and letting DH deal with it instead! i want to run in there and read over his shoulder and take control of this whole mess... but i know i shouldn't... i just wish this could be a HAPPY thing! gahhhh why does she have to make it so hard...?
