Yes, I agree with you guys.
At one point or the other, on one side or the other, there's going to be attraction. I had a guy BFF. We were really close; we practically grew up together. Been friends since 5 years old. We've never separated until he and I had to go to college and departed our own ways. We didn't see each other as much but still kept in touch as much as we could. After a few years, we both graduated and hung out like usual. We became even closer because we've both matured and shared the same morals and ideologies and stuff. Out of the blue, this one autumn Sunday, I looked at him and he seemed different. It was then I realized that I was beginning to like him more than a friend. It just hit me. I never thought that would ever happen, but it did. Come to find out, he had always liked me but didn't pursue me because he didn't want to lose our friendship. Well, he's dating someone else now and that was many many years ago but yeah, from experience, boys and girls can't be just friends.
And these types of relationships hurt the most too. When you lose him, not only are you losing a man you care for but also a best friend. It's like taking a huge chunk out of your heart.
