Should I keep secrets from my partner?

If you’re looking for a long-term, committed relationship, then you want to be with the person who appreciates your ability to communicate your feelings, not withhold them. — Dreamstime/TNS

I recently got a question from someone on my mailing list, not a client (so I don’t know their details intimately) but a person who seeks dating advice, and that question was this:

“Is it good to have some secrets in a relationship? Isn’t that one of the many things that attracts a person... a little mystery? Are there things that you should always keep to yourself?”
