What if my husband comes back from reading my horoscope and says I'm having an affair?

I'll tell you a way, as long as you don't have that affair, but your husband believes in superstition, that's easy. Next time, you can take his horoscope to the fortune teller and try what the fortune teller says. If your husband doesn't say so, then he is lying and testing your reaction. You can also go home and say that he is having an affair and see what he does.
