I agree with Siana!
If you are in a serious relationship with your boyfriend, not just some 2 week thing, then you've probably got a problem is you are feeling someting for someone else...
But if this isn't a very serious relationship, and your liking someone else is just a 5 second cruch, then that is kinda normal I suppose!!!
But just remember, cheating on someone is v bad, and the kindof thing that you will always remember that you have done...
