Possesiveness may be. I know its wrong?

What I understand from this is that you are deeply attached to your friend and wish to take the friendship to the next level. Being interested in a person of the same sex you might be worried if he has trouble accepting his own sexuality which might affect his acceptance of a relationship. I would suggest, give him some time to work out his own conflicts and honestly, there is no way to know if someone really loves you or not. All you can do is communicate your feelings clearly to him and help him muster courage to accept himself and your relationship. If the response is positive then it’s perfect for you, however if it is negative, then honestly tell me, do you really wish to be in a romantic relationship with someone who does not value or respect your presence and significance in his life? You deserve much much more in life and he too needs time to evaluate his feelings for you.
