God Forbid Women are Single *eye roll*

Although the full  reasoning behind Elizabeth not wanting to marry is never know in full detail, we know it worked for her.  Why though, would she not marry, never have children,  never have a "love"?  She probably never knew a "family life" (although being queen she most likely wouldn't have had much time).  Did she do this only for the good of her kingdom, so she could be the best leader they needed? Or did she have other private intentions that haven't been reveled?  Was she afraid of her husband overtaking her power? There's many reasons, some we know for sure, but maybe there are others that have never been revealed.
