This doesn't have to do with my W, and I'm not trying to manipulate a reaction from her with this.
I think what Kettricken is saying is, is this healthy for me? Is it fair to the other person? This woman does know me, and my W, and I said to her - you know where I am with this. I do not want to be selfish, I do not want to "replace" my W, and I want any next relationship I have to be based on a real foundation, not a reaction.
She has come out of a bad marriage, but is further along in the process. I think she understands all this.
I do not plan to be irresponsible or reckless, and I'm trying to be really aware. It would be EASY to blind myself to red flags.
So - thank you everyone, I value your opinions, supportive and critical.
That said, the hardest part is watching my W go through this now.
