ok.......I feel you are a very smart young lady.
Your pro's and con list is a great idea.
I am a mother of 2, one step and one biological. I was happily married to a great husband that helped me a great deal with the kids. I had NO other support system. I moved frequently all over the US....
You already have a great career and support system where you live and you don't love the father of your child. Stay true to yourself! Stay with your career because intellectually you need that to be a happy thriving Mom.............Moving to a foreign country with the only support system of a man you don't love is doomed to fail.
If the dad needs to see his child, let him come to the US, but never take the child out of the country.
Just my 2cents!
