Update and done...
Wanted to report this earlier but every time I went to post [and got anything written] the computer turned off. Weird as it was seemingly not the proper time to do the report.
After much deliberation and much thought, moreover much delving over all of your words and pondering your wisdom, I did what many of you suggested.
I called. No email. No answer, which was all right too.
The message was loving, concerned, genuine, supportive, slow and easy in speech and I think, well delivered. I did not mention what I shouldn't and did speak of what I should, just as you all eluded to.
It dawned on me that I can be [and am] bigger than this problem. More so, so is the One that lead me in the right direction, which was to not hit send when I'd originally written that email.
I told her that I was proud of her and her efforts toward her beautiful family. I told her how proud I was of everything that she and her husband had accomplished in their young life together, as man and wife. I told her how much I am looking forward to being with the little girls come January and to please let me know of the best dates for her so I can be of the most help. I asked her how she's feeling and told her that I know how hard it is from my stand point, which is no where near what she is dealing with. And said that I know this is a hard time with pregnancy and her husband being gone finishing his schooling when its the holidays, she's a working mommy, has to take care of the girls and all the while being pregnant with their little one. I promised her that things will look up and soon, and that all of this, that looks like a big empty hole right now will be blossom into something truly wonderful for their family. I asked her to kiss the baby's for me, both of them, then added “no all 3 of them“, meaning the little one in her tummy, then said, all 4 of you, make sure all of you get kisses from me. I finished by telling her I love her and wished her a beautiful day. My tone was low and slow and soft, my words not rushed and honestly, it was something that wasn't that hard to do and like someone said, she may be reaching out, knowing she's done wrong, but maybe is seeing if I love her anyway.
Thank you to all who helped me with this, this was a tender time for me and I think it's all going to improve with time. I am so blessed for stopping my action and asking for advice here.
