First thing first, need to worry about yourself and how you feel. It’s up to the other people to deal with how they react to your sexuality. It’s not your problem and remember that. Your family will be there for you no matter what the issue is. Since this gentlemen is in a relationship, I would take the time to think this over. I don’t think it’s ever a good idea to take away from someone else’s relationship. Take time for yourself and accept yourself for all of your amazing qualities. As a human we will never have all of the answers. =) It just comes down to acceptance of yourself everyday. I wish you the best on your journey. You are the most important in your world!
