To each his own.
I did reach my decision not only based on the advices given here but with much thought and discussion with my dear FH (future husband) and also with my kids... the to follow that i was thinking before was my sole decision, i didn't gave all the other persons involved (my kids and my FH) any chance to sway me the other way before. (do i sound like hitler?.... not really, just being an overprotective paranoid mom

)
it's been 8 years now since i kicked my sperm donor (father of my kids who never paid child support ever) out of my parents house and the longest time that i was ever away from my kids was when i had my 2months training in manila years ago for a pharmaceutical company and subsequent 4months initial assignment in another city before i was finally transfered in my hometown. (im from davao so manila is miles away from home)... and yes it was heartbreaking. i have almost forgotten about those days and the replies i got here transposed me back to those times when i would spend every night crying and missing my children...
and again, to each his own. there are indeed valid reasons for choosing the to follow route like the PM i received from a single mom whose child will be on her 4th year in high school come June this year. she said she doesn't want to rob her child of the enjoyment of graduating with her peers, and i could understand coz i, myself, will never trade my high school days esp. my last year in high school with my friends, whom i have formed lifelong bond, for anything else... if that had been the case for me, i would have stood my ground in the to follow path also.
there are other valid reasons and unique situations that really calls for "to follow" but after inner deliberation, i must admit my reasons didn't make the cut.
On a lighter note, fedex online tracking states that my documents will be delivered wednesday, jan. 23. YAY!!!... and if there won't be any problems we might be able to send our application off to USCIS next week

. LET THE WAITING GAME BEGIN!!!

I'm raring to add our time line here!
Again, thank you everyone for sharing your thoughts. I know you will still be part of our journey for many months to come (years even, with AOS and whatever other USCIS things still looming ahead)... and knowing that, somehow put my heart and mind at rest coz i know, help with questions and sympathy for any frustrations we might encounter along the road is just a few keyboard strokes away
God bless you all!
