Many relationships parish because of poor communication. It is a lack of knowledge that makes so many women vulnerable. If you believe you may be losing him there are two things you should consider:
First, reconsider your initial role in the relationship. Were you just friends, were you friends with benefits, or were you companions?
If you are just friends, you are two people who share similar interest and enjoy each others company. There’s a sense of comfort and security in your relationship because you are not looking for the other person to be anything but a friend and confidant.
If you are friends with benefits, you’ve taken the relationship to a level of closeness. The problem here, however, is that you’re not requiring anything in return for giving yourself away. The act may have happened accidentally, or it may have been a carefully planned encounter. Either way the lovemaking sends different signals to each of you.
If you are just a companion, you are a trophy to be put on display. Something about you makes him proud to have others see him with you. Your beauty, style, wealth, or popularity stroke his ego. Others look approvingly at him because you are on his arm. He may not want anything else from you, or closeness may be the benefit that comes after a great evening, but the truth is he likes showing you off.
After re-evaluating your role, discuss with him what you think it is and ask him what he wants it to be. You may find that you want more than he’s willing to offer, or you may realize he’s ready to take you both to a different and better place.
