Sorry to hear you had trouble with your MIL too, Lovemarmite. But it sounds like things are better now?
I'm lucky that my PIL are normal human beings. It quite nice to have a real set of parents available :) We do have different outlooks on a number of things, but at least they interact with us like we are also people.
Since my Mum got a computer last year and discovered video chat, my DH has been able to hear both sides of our conversations (when before he could only hear mine on the phone), and confirmed to me that they just don't sound like any normal conversation he's ever experienced. He said it's more like they're reading from some sort of script with pauses for me to speak, but don't actually respond to anything I say. He said he finally understood why I would keep saying the same thing over and over again -- like in my above example, I'd go through the explanation of why we didn't need childcare yet 3-4 times, as my Mum would provide follow-up questions as if I had answered "Oh, quite well, we've talked to a few now", still with the assumption that I am interviewing people... The one big exception was when I phoned to say I was pregnant :) That actually got a response.
And I'm afraid moving across an ocean isn't the panacea that it might seem, so do be cautious! I found that now my Mum must see me every year, in person, involving either me flying to her or her flying there, whereas when we lived only a 6-hr drive apart (a short distance in the US), I think they came down for my wedding and that was the only time we met in person in 4 years; I lived a 14-hr drive away (a longer time frame than it takes to fly between us now), and we only had 2 visits in 6 years. Yet now I'm "far away" so it's especially important to spend months discussing and arranging the next visit. Plus we must video chat at least once a week -- and now that she's found video chat it doesn't count if we don't use it. So it's multiple phone calls a week to arrange the weekly video chat, sigh.
Ugh I realise that in the above I must look absolutely horrible it's not that I think seeing my parents once a year is an onerous duty (I know many people visit family way more than that!); in fact, the years in the States without physical interaction were due mostly to their obstruction. I invited them over for Xmas, tried to arrange Easter visits, etc., but as I wasn't doing things "properly" they refused to come or told me not to bother. And they'd find the oddest excuses, usually blaming other people somehow, for why I shouldn't visit or they couldn't travel. This is part of why it takes months of discussion to arrange each yearly visit now...
Okay, now I'm glad I named-changed so no one can connect my other name with this horrible, ungrateful daughter 
In my defense, I do try to maintain good interactions with them and I think they will be super grandparents.
