My instincts tells me you shouldn't push it. If someone reminds you too much of your ex or how your ex once was, there's a reason for that. All too often we get involved with someone just like our former spouses -- the battlefields of are littered with the accounts of such failed R's.
Dday, given that you're still expressing some non too dispassionate sentiments about your former spouse, perhaps you need to think more along the lines of friendships with other folks, and nothing serious -- stay "casual", in other words. At least until you've gotten some more time in C'ing under your belt and can view things in your old R with more indifference. You seem to have a few too many strings tieing you to your ex for now, and the jitters you're feeling are natural.
