Jeeezus, she's still a woman, she's allowed to fantasize about having kids without it making her a simpering lovesick teenager. A lot of women, strong or otherwise, do fantasize about having kids they just don't make it public knowledge to the guys 'cause they don't want to come across as crazy desperate.
A lot of non christians get christian weddings because they are traditional or they have christian partners. You may not like it, it may be hypocritical but its called compromise, and compromise is what you do when you love someone.
Just because she thinks about what Tom may want doesn't make her "the little woman" either, it just makes her thoughtful.
