This one's actualy pretty simple to answer. If your love intrest doesn't agree with your other passions, then you aren't optimaly matched. You now have two options;
A: stay with her anyway, and find that differences actualy run deeper than this one issue, and end up losing "the spark" or even getting divorced.
B: move on and find a woman you have more in common with. There are always more fish in the sea.
I'm all for meeting half way, taking into account the feelings of your partner. I'm a very caring and compassionate person. However, like I said, if there really are "it goes or I do" issues, it's symptomatic of deeper issues that aren't really resolvable and it's best for both parties to move on.
In response to any replies, the exceptions prove the rule.
This can be proven because we already know that "rule" means what's most likely to happen(or average), and that laws are made to be broken, and an exception is in effect breaking the rule. Thus it establishes the rule as law.
This is further evidenced by the phrases "rule of law" and "law of averages" firmly establishing a link between these terms.
