If you're a woman and you don't think this then don't bother responding. But the overwhelming majority of women I've met seem to think this way.

If you want a relationship then can't you simply use your words and ask about it?

If you don't the answer you want then can't you just stop seeing him?

What if the man hasn't decided whether he wants a relationship with you or not? What is he supposed to disclose?

Why do you feel that it's a problem when men aren't a completely open book?
