3. Keep being the individual you were before you got in the relationship. When you give up aspects of yourself, you stop being the person your partner fell in love with. When you mold yourself to suit your partner, whether he or she asks for it or not, you lose your vitality and your relationship suffers.
4. Allow your partner to keep his/her friends (regardless of gender). When you restrict your partner's movement, he/she will start to resent you and may become less straightforward to avoid dealing with your reaction. Your partner needs to keep his/her friends for all the same reasons you need to keep yours. By letting your partner be free, you ensure that you're his/ her "real" choice. You don't want someone to be with you out of obligation, guilt or fear. You want it to be because they love you (and trust you) for who you are and because you love them for exactly the same reason.
5. Don't lie to your relationship partner, even by omission. This means not engaging in activities with other men or women you are not willing to disclose to your partner. Deceptions may seem self-preserving in the moment but they will only drive you apart in the long run. When people find out they've been deceived by a loved one, they will often lose any trust in that person, which then leads to either heightened jealousy, attempts to control or rejection.
