Just need to get this off my chest and see what all you wonderful people think...

My best friend of forever came out to me yesterday morning that she was a sub. She had a light bulb moment in a text conversation with a co-worker, & the flood gates opened. I've talked to my Sir about this and we both at crossroads about how I should respond. I'm also having confused feelings, part of me really want to see if she would like join our relationship as another sub.
