Like LongdistanceI have been there and done that.
Our relationship was ok before we left, not amazing. He has a high powered job and was asked for as a secondment to Australia. 2 years.
We had been in Brisbane for 12 months when his role moved to Perth. That's about 4000 miles. He would come home once a month for a weekend, there was no money to assist us to move over - we had a two year contract on a house that he said was unbreakable. It was shit.
I am stubborn I managed to negotiate a way out of the contract, packed up the DC and drove across Australia- doing the last thousand miles by train.
Dh was not there to meet us - he had a meeting.
Anyway, the two years came to a close, I packed up the kids stuff and went to pack his and was told he had to finish the project first.
I came home with the DC without him thank fuck he was there a further 2.5 years, visiting us 3 times a year for a fortnight or so.
I fantasised about divorce but came to the conclusion that it would change nothing, so what was the point.
He finally came back to the UK last July, and I cannot tell you that it has been easy. The levels of resentment I feel are outrageous. We lost a couple of family members while he was away and he couldn't get back. I had major spinal surgery (to prevent paralysis - that kind of major) and he couldn't get back. My dearest ds was diagnosed with type 1 diabetes while he was home for one of his stays - ds had been discharged from hospital for 3 days when he went back again.
I basically had a nervous breakdown with the stress of it all.
I normally suggest having your eyes open on other threads about moving to Oz, it can be a beautiful place and some of the people are really lovely, but in your case,
DON'T DO IT.
Oh and he has PR now (of course) and so do the DC. I have told him that we will not enter Australia for as much as a holiday until it is no longer valid.
