What would happen if I was to relocate?: Response to relocating interstate
I read your post today and feel saddened that you have found yourself in this situation. However, over the past 11 years your ex has had to be apart from his children who in the hearts of most Dad's are precious - It hurts like hell being away from them for even short times. Regardless of how much time your consent order specifies, or how generous you feel you are being by allowing extra visits, it will never really suffice. Your Fiancee has had more contact and input in the lives of your children for some time now and it must be disenfranchising and demeaning for your ex to have to accept that. Eleven years is a long time and he has had time to adjust, but now he is faced with an emotional upheaval of enormous magnitude - interstate visits. Are you going to fund his long distant phone calls, airfares, car rental and accommodation costs, in addition to continuing to seek ongoing child support? It will strike him on two fronts with the burden of increased costs and the reality that he is now even more isolated from them than before. You suggest in your post that you have considered him and the children, but have you? The children will say what they need to say to try and keep both parents happy. I have seen it with my own kids and would hazard a guess that most of those estranged dad's and mum's out there have witnessed it too. It is completely natural for them to do this and placing them in a situation where they have to decide, only makes them feel torn and confused. As for you, it is wonderful that you can fulfil this opportunity to better yourself and your new relationship, but again it will be at the expense of your ex and his long term relationship with his children.
I urge you to address your ex in writing if he is not willing to speak. Perhaps when the children are in their late teens and more emotionally cognisant of the ramifications of being so far away from their father, this will make things smoother and less potentially litigious. If you were to make an attempt to push past your ex and do what you suggested by running away, people are going to get hurt and in the long term that will only lead to resentment against you.
