I have spent months away from my husband due to his work. A couple doesn't have to do that to be considered "healthy." In that post, I had been away from my husband for around 5 days. I will spend four days without him next week. We do not cling to each other, but we don't need that time apart. It happens because of his work, but I am not trying to get away from him. I get more than enough me-time as a housewife while he works twelve hour days/nights.
I wrote that post to say that I never feel the need to run from him, and I cherish the time we get together. It was more about using our time apart to strengthen our relationship instead of being upset about it.
I hope that makes sense! Thanks! (:
