Sorry to read your story. For sure it's not an easy situation to be in especially when you have kids who are effected with this situation. Well I am from Germany too but my soon to be ex wife lives here too. Luckily we don't have kids but after we filed for divorce I had to put property for sale in Germany as half of it belongs to her. This year is not a good one for me fore sure. So I can understand what you are going through and everything will be fine sooner or later, we just have to wait.
