Hi,
My wife, children and I also spend lots of time apart. I spend approx 8 months away out of the country per year. (Usually 8 weeks away, 4 weeks home). It is hard, but technology such as zoom, WhatsApp etc make communication much easier than years ago. It’s important your partner invests time daily with zoom calls etc, as it’s the next best thing to actually physically bring there in person.
Its also important to “Make the most of home time”, make it the best period of time before you are all separated once again.
Personally, I get 4 months off per year, which is more than a standard job in the UK, I devote my entire energy towards my wife and children whilst home, I do not come home and “go out with my friends”, it’s all about focusing on my wife and children. If I do meet friends then it’s always a joint thing with their family and my family.
For example, I know work colleagues who go home and split their time between family and friends, my view is if I’ve been away, come home, go out and get drunk and hungover the next day, then it’s a day written off, where I could have spent precious time with my wife and children.
In short, working away can work, but it’s important to stay communicated. Even on a sexual wife/husband part, you are not physically together but there are ways to keep things interesting and exciting. Video, photos, etc. it’s so important to maintain a sexual connection and not allow it to die away.
Hope that helps
