I read jlp's post on your other thread . . . sound strategy.
Time together will enable you to feel her out . . . but beware . . . JW "feeding" can quickly create distance.
Also . . . just preserving your great relationship will of itself hold up a "cost" to her for getting in too deep. Especially if the closing years are a concern . . . close to you is a superior way to spend them . . . hopefully she will see that . . . just keep loving her bigtime.
Good luck to you . . . and stay with us on this one
