Feel like crying and puking my guts out

We went from a planned family vacation to Florida to divorce cause things were not working out, then to just him and the kids going to FL but I was still getting to see him, to him just coming back and spending time with the kids and still seeing each others face to now him wanting to fly the kids to meet him and his family and not seeing each other at all.  When he told me my stomach just turn and I just wanted to puke,  I knew that was a possibility but it becoming a reality hurts more than I thought.  I just want to cry and cry, knowing that your marriage is over and facing the reality of it is so overwhelming, knowing that I won't see his face even though I know is over is painful - wasn't expecting it for it to hurt this much - haven't seen him in 7 months, by the time he see the kids it would be 10 months and by the time he finally comes back from Afghanistan it would be a yr without seeing each other - he has moved on with his life and even though I'm doing everything to be able to move on I feel stuck!!!!!! Stuck to this emotions, stuck like a leech and I can't let go when I know I need to..........so frustrated right now!!!!!!!!!!!!
