That sounds like a really nice life honestly, and it sounds like if you need any emotional support you get it from your family or your few close friends. Some people need more than that, whether they realize it or not, though.

I can't say what you need, I don't know you. Maybe you could ask your wife if she thinks you need more friends? If she says something like "eh? Why?" then you're probably fine. But if you get a long pause and then, "Well, it wouldn't hurt..." then maybe you should ask her more questions.
