Man, it's normal for a husband to limit is "spending time" with female friends.
If you're not realizing that you're not putting your relationship with your W first.
It's that simple. Really, really is.
So it appears this is your problem not hers.
Most married successful husbands can cultivate female friends in the same way you've described "comes naturally" to you.
You're really not that special in that respect.
It's just that most of these same men realize it's not something a married man does.
You have to decide.
Or eventually she will take to heart you want to spend time with other women, she'll stop talking to you about it, and she'll harden her heart.
Then you may lose her.
