It has been a year since me and my boyfriend have been together. I really love him, but all of a sudden I have crush on othe guy , he works in office where I have trainee. I noticed that I think of him all the time , I love his voice, could listen all day .. love to look at him, I am so happy when I see him, I dream to kiss him and hug him.. I fantasize everyday about him I can't help it. But I know between us won't be anything because he is engaged and he is 26, I am 20. I also wouldn't leave my boyfriend never! But I feel guilty , I can't help it. Is this wrong? is this normal ? or am I really bad?
