You know it's not going to work. You will always want more. Find some other friends.
Are you having sex with him? If so it could just be that when a girl ******* the brain releases oxytocin, which causes you to feel more attached. If you are not having sex with him, it might just be that you are lonely. You can still just be friends with someone who you love. <br />
I am in love with someone I can never be with, so we are just friends.<br />
Good luck.<br />
