You're a personal blogger. You meet someone & they know that you're a personal blogger from the beginning.
You guys start dating & it gets serious. During the relationship, you blog about your SO & about your relationship. Your SO is fine with you writing about your relationship and about them.
You & your SO get married.
Would you stop blogging about them & the relationship at that point?
If your spouse asked you to not blog about them & the relationship now that you are married, would you comply?
If your spouse was the blogger, would you want them to not write about you & your marriage?
