We've been together 7 years, living together 6 years, and married for 3 years. We've never had a real argument. We've had little moments when one of us is a bit annoyed or moody, but we end up just apologizing and laughing it off minutes later. She's my best friend.
Now, we are both happy, but I often worry whether or not what we are doing is healthy. We really only like to hang out with each other. We do have friends (mutual and individual friends). I've gone out dancing alone with my friends and so has she. We trust each other 100% so this isn't a possessiveness issue. It's more that we enjoy each other's company so much that we find hanging out with others to be a bit exhausting. If we go hang out with friends even if it is out to dinner or at their place for movies, we end up feeling SUPER grateful that the evening is over a few hours later and we can finally be alone together. We've cancelled plans dozens of times so that we can go out swimming together, watch movies and order Chinese food, etc.
Is this unhealthy? Every time I google it, it says that time apart is essential for a good relationship but the only time we have time apart is when we go to work or if I am working and she goes to visit her family for the weekend and I can't come. I've talked to her about it, and we both agree that we are very happy with the way things are.
