I'm not going to tell my husband that I'm going to a psychic.
Is there a reason you wouldn't tell your husband?
He'd probably be rude and make fun of me for it.
If you think he would object or be rude to you about it then it makes sense to want to keep it private. It's not like you're doing something that will have a huge impact on your relationship so theres no reason to tell him about it unless he asks.
He might be fine with it, perhaps I'll go and tell him about it.
Visiting a psychic isn't a huge deal and if you want to keep it private that's fine, but if you choose to share it with your husband, that's fine too. He might poke fun in a joking manner, but he probably won't be hurtful about it.
