Yes, I have. I think it’s important to be honest with your friends, and if you really care about them, you’ll want to be upfront about your feelings. Plus, it can be really awkward if you’re not honest and one of you eventually ends up confessing their love for the other.
I was really scared when I confessed my feelings to my best friend, but he actually took it pretty well. We talked about it for a while and decided that we wanted to give dating a try. It’s been a few months now and things are going great.
