My friend of many years, who I adore and have absolutely no ill will towards, does not know. The relationship she had with this person was minimal and is long over (better than 3 years) but she definitely had feelings for him which, sadly for her, he did not return. She has since moved on and is happy in a relationship with someone who adores her as much as she adores him. 

With respect to the 'ex', we have definitely hit it off. It's been a very long time since I felt this naturally and passionately attracted to someone and he seems to feel the same. However, I have strong reservations about hurting my friend by ever taking our relationship public. All of the interaction between he & I currently happens behind closed doors as our dates are limited to his place or mine. I know that if ever he and I were to get serious, I would have to have a conversation with my friend and be willing to non-defensively receive any hard feelings she might have about it. I truly do not relish the idea of hurting her in any way and I deeply regret that I've found so much happiness with her ex. 

So, have I done the worst or are there a variety of perspectives on this?
