Sounds more like 'trust' issues than not being able to love. If you have plenty of friends, you have plenty of love. Friendship is a different kind of love though. If you were to fall in love with a woman, it would involve intimacy. If it becomes full-time, it would involve the woman in your life. You would have to trust someone very much in order to let them become a part of who you are. When the right lady comes along, I imagine she'll be a friend first. Nothing wrong with that. Let yourself be for now and get and give your love and affection from friends. It will help you slowly develop trust in people and give you a support base. When a girl comes along that you really like, your friends will be there to help you take the next step.
