I married one op. He was away three months at a time. Three months on three months off. To be fair it suited me just fine. I just got on with it. You send weekly telegrams with a limited amount of words to them, they can’t contact you back.
Anything you write is read before it’s passed on, as no bad news is given to them when under the water, so if for example someone close gets ill or dies, their relationship ends, they won’t be told till they surface, they even perform surgery on the submarine where required. Your telegram would be redacted or simply not passed on.
When we had our daughter though he put his notice in, as he had been land based and lecturing for a number of years before that and for the first few months of her life, then he was sent back to sea, as it was a five year lecturer role and time was up, and as a tiny tot three months is a long time and she was forgetting him and asking other random men if they would be her dad Ie in the supermarket.🤣
So he put his notice in after the second deployment, when she was eighteen months and was out by the time she was three, as it was an eighteen month notice period. He also went back to lecturing during his notice period and was land based.
For me, I worked, had friends, and was perfectly able to care for our daughter when he was away, and perfectly happy, I also didn’t ask him to come out, it was his idea and decision.
Please ignore those generalising about the personality type of a sub mariner, I’ve clearly met many of them, and there is no one personality type, they are all different, just like in any other job. There is also different levels of seniority and types of job.
Please also remember that just because he is on the subs now, it doesn’t mean he always will be, depending on his role and rank he will have other opportunities, as said my husband lectured for several years. There are many land based roles he could move into unless he’s not very capable and destined to stay a relatively junior non commissioned for ever more or he desires to stay on the subs.
