I don't have Bruce's finesse, so my tool would be the proverbial 2"x4". But no whacks for you. Again, this post-D DBing is frontierland, and we are crossing virgin ground.
You seem to have a handle on the subtle nature of your XW, and her exploration of adopting a baby, and mentioning that to her D was perhaps 1) a testing of your interest in her; 2) evidence of her loneliness and need for connection; and 3) a sign of yet more internal chaos.
Wes, she came once more to you in a time of need/concern. And you took care of her - with a very big AOS. Sure, you slipped in your desire to be the father(sperm donor?) of her very hypothetical baby, but I'd let it go, and not mention it again. Does she seem appreciative of your AOS or get closer to you afterward (meaning during the next week or so)?
Her saying that she has "no one to have one with" is great news. Much better than her saying she's planning to have John Mayer's baby or to be in an R w/ an OM, and start mentioning that.
IMHO, a tad of mystery (while staying positive and continuing with timely AOS and WOA) might help your sitch. If she thinks that she has you in her pocket, this may continue this semi-limbo your sitch is experiencing.

Okay, I won't. I've been relaxed today. I'm not stressing having thrown that out there and the R talk (if you can call me doing most of the talking) that surrounded it. It will either be positive, negative, or not change anything. I have no control over how she responds to things. But, despite that, I think I made some love bank deposits in other ways.
So let's see...considering the deposits I've made minus the withdrawals, I'm only about 2000 love units in the red. That's a definite improvement from the all time low balance, when I was 200K in the hole.

Artificial insemination will require a "technician" of one sort or another. Although I specialize in the bovine variety, I'm available with a week's notice.
That was my little song snippet quote. It's quite on the board the last couple days. Is everyone running out of steam?
Here's my updates: Went to bingo last night with X's sister. She's got her own love life problems that we discussed. She asked if I thought her sister and I would ever be back together and I told her "I'd like to". She doesn't have deep talks with her sister so I'm not all that concerned about her telling her anything.
After that I went home and made myself something to eat. It wasn't very long before X called. I take this as a positive...this time there wasn't a reason. She asked what I was doing, said she was going for icecream, and asked if I wanted her to swing by and get me.
We had a nice discussion of stuff in the yard for a bit then ran for icecream, basically talking the entire time. We mainly focused on her daughter's difficulties with school. I was annoyed how "no child left behind" in her case seemed to mean "we'll move you to the next grade whether you are learning at the same pace as your peers or not". We didn't discuss what I told her the night before or touch on us at all. I think it is a positive that she didn't go into hiding. I also got another chance to get some QT with her.
That's all for now. I'm keeping my little song snippet in mind because of the important key words..."No rush", "I won't rush your heart until you feel on solid ground, until your strength is found".
