You haven't learned to be independent. You can become so by volunteering at something you are interested in. Take up a sport, artwork, digital imagery, photography and set out on your own. No one (male/female) wants to feel trapped by their mate all the time. You have to trust your partner and let them go out with their male friends and you go out with your female friends on occasion. Give it a shot! Sit down and write on a piece of paper what makes you feel so afraid of getting out there and doing things on your own or with friends. Once you have written the list you should have your answer and you can work on it. You've got to start somewhere!
