If she went out partying, random night out, not a special occasion, she is doing something behind your back.
I'm not married, but if she cares about you and your dad did nothing to her or dislikes her you really have issues in your marriage.
Yes, if she didn't care, then it would be an issue.
However, people are NEVER as black&white as that - there's way more issues and complications underlying. We like to jump to conclusions that are black & white, though: "she doesn't want to go along, so she must not care". BIG assumption!
That's what the book that I recommended explains - it explains the type of assumptions you are making, the role of feelings and how your identity influences what you say (or don't say). It isn't a book about marriage - just difficult conversations.
