Sounds like you've thought things through. Since she has had the opportunity to bow out of any or all of the get-togethers, I would agree that she wants to see you. As you know, I played this little game of see you a bunch with my XW and it led to months of frustration that nothing was moving forward. Perhaps, like my XW, yours wants to be around you, but is looking for excuses why she wouldn't want to try again. I don't know what the best suggestion is. Perhaps riding this patiently out for awhile is the best choice and if you see no progress maybe you should start doing things to protect yourself and move along with your life. I don't think you'll be happy if you look back on 2006 and find you spent a whole year in which nothing changed between the two of you.
Agree, don't confront her yet, but when you've reached your wits end and can't continue on with this anymore, perhaps you should give notice that you just need to know where you stand.
