Good interaction with W. This is tough stuff indeed!
Bug has covered some points very well. So I just want to add about the Friday night date.
This is a long post, sorry. I should just have wrote the last thing she said to me. "Friday, you can take me out Friday. I will try if you will try." So I have a date with my W on Friday.
My thought is to slowly romance W and focus on her good qualities. Don't over do this. Perhaps do things that we did way back on our first dates such as commenting on how her hair accentuates her face. Make one or two comments like that to your W. Then go with the flow and adjust accordingly.
Perhaps before you go on a date, read up on the latest news or some joke. Make it more interesting instead of just you and the kids. Or say that 1.3 million Earths could fit the Sun. [It is just me...I like fun factoids like this and makes for an interesting convos!]
