Sounds like a bratty little child is not getting his way, so he is trying to be spiteful! So immature!!!
Let him collect his skiis! Deep inside he probably needs to have something to do to occupy his time since he cant be normal and be in the baby's life. Skiing will NOT fill his void!!!
I am just sad for him because he should want to be in the same country and want to participate in his child's lifeand so on for his own sake, and because he wants to. No, its not easier for usbut it would help you raise the baby and also be beneficial (although not necessary) for the child. Do you girls realize that in all of this we can not even focus on the separation or divorce because new babies make things so not about us! Like our M are completely back burned and focus on them being parents. Not Fair At All!!! I do believe he doesnt know how to do this coparenting thing without him feeling like it could only work if the two of you are together. But Shame on him for not wanting to work out a normal plan in simply co-parenting. Wonder if he is getting pressure from OW. If so, he will end up resenting her sooner than later... and sucks for her to not be normal enough to say HEY GUY... what kind of person are you to leave your newborn child!!!
If I were you I would still consider a mediator... not a counselor as you said, but someone to help bring things to a calm resolution.
