Yes that is what friends are for. They should accept who you are no matter what. Now your family may be another issue. Have they ever stated before that they have had a problem with same gender relationships? It may be different if they are usually an open minded family. Before you tell your family I would casually try to bring it up and see what their opinion about it is. But eventually you will have to tell them if this how you choose to live your life. Whether it is with a male of female. Im straight, but I accept it. You can't help who you love or care about. Or even who you are attracted to.
