It is not that I would not have a relationship with her daughter because it seems like you had one with her before all of this. That in itself is not a bad thing.
However, I would tread lightly where daughter talks about her Mom. It is akin to walking through a minefield... tread lightly and carefully.
Don't fall into the trap of what of people think, either. It doesn't matter. These people have little to no vested interest in the outcome of what is happening. Just smile and nod.
Just a thought... While telling your W that you love her may not be good DB'ing... telling her that you know that she doesn't want to hear it is showing a lack of respect. You need to show respect to get some back.
I also feel like your text message about the motorcycle accident was made to invoke a response from her. That is not right. It seems as though you were trying to generate some sympathy out of it, too. Then you seemed disappointed when it didn't come.
BTW... I started reading the link you posted. Seems interesting and I plan on following up on that.
