I'm a stay at home mum and hubby travel for work very often. There's no acceptable frequency, as that's his job and he's the sole breadwinner. He's usually away for 3-4 weeks, longest period is 3 months. When he's back, he'll rest for 1-2 weeks before he travel again. As his job is related to marine, sometimes we'll be without any form of communication throughout. Otherwise it'll be emails every few days.
I have 3 kids, youngest at 22 mths. I have a part time cleaner coming in twice a month for major cleaning like windows/toilets/fans/stove etc. I'll do my own cleaning every few days on my own.
Initially I'll feel very lonely and sad when he's away, but after so many years, I'm getting used to it. I have friends who chat with me in whatsapp almost everyday. There'll be gatherings, lunch dates, playdates pretty often too. My mum stay near me, so I'll go over during the weekends. As I drive, I'm usually out with my kids shopping and eating, so I'm seldom bored. :P
I've been a stay at home mum for the past 3 years. I'm those independent type, so I can handle these types of situation pretty well.
My advice to you would be to have more friends, and if you have kids, gather your friends for playdates and gathering so you'll not be too bored. The initial separation will be very hard, but as time goes by, you'll get used to it soon. Having friends and family around you helps.
