Divorced-not done-But wondering ?

[JJAC2005]

I need a little help right now....
I recently came back from a little vacation and am finding a lot of reminders of my wife and family everywhere along the way, and I have a very special date approaching to my "past life" situation as well.
I am feeling the urge to do 2 things....and they both have to do with contact.
I have not reached out in any way to my ex since early March, when I sent her a short little email to inform her that my mother had been hospitalized, to which she expressed a little concern, but didn't offer any more communication other than best wishes and prayers, so its been about 6 weeks (typical urge)
My wife will be having a Birthday coming up in May and while on vacation I thought of a perfect gift, and that sparked me having some sort of delusional fantasy that if I wrote her a short little note to accompany the card, it just might start a little dialog between us. The other form of contact was another attempt at a heartfelt letter about my thoughts and feelings....along with my desires to possibly see the kids again.
Both forms are chances....taking a chance that it could spark something (50/50 either way)
Now aside from my still missing my family my life seems to be picking up, busier and busier with projects, goals are being met, new opportunities popping up, and even more changes coming down the road. So, I have been doing pretty good overall....
I just cant get them out of my mind or heart for very long and honestly don't want to, but the ache still gets to me more than I want to admit.
So, I need to know if patience is my best course (my hardest lesson to learn) or if I send her a little reminder in May for her B-day would be a bad thing?
I'm confident now that she misses me less and less, probably not remotely curious as to what I am doing, so I guess I answered my own question....it wont do any good....but if it wont do any harm, why not take the chance?
