True love can be a double-edged sword: I've been in love for years with someone I can't be with. We keep in touch on a friendly basis and he knows how I feel about him and is very understanding, but he's just not interested in a relationship with me.
What can you do? I don't press, because at the end of the day his happiness is more important to me than my own, so as long as he's okay I'll bear my burden gladly. But I know I'll never be able to fully give myself to anyone else, since no matter who it is, they'd always be second choice, and that's not fair to anyone who's worth it in the first place.
