In my opinion, a healthy relationship involves mutual respect, communication and listening to your partner's needs. Many of us only hear, but don't pay attention to the message that is being conveyed. Second, a healthy relationship involves trust and how do you establish trust? You establish trust by getting to know each other well, asking lots of questions even those questions that you feel uncomfortable asking, well you must do so if you want to learn about your partner and establish an emotional connection. Third, you need to establish and set boundaries from the beginning as to what is acceptable and what isn't. When there is trust and communication, then there's no reason to hide stuff from each other. Another thing that I wanted to mention is that it is okay for your partner to have male and female friends just as long as they introduce you as his or her girlfriend/ boyfriend, husband wife etc. Now, I am only the Love Doctor.... lol.
