Divorce between ex-girlfriend and current husband should be "parting" in the dream. According to the contrary between dreams and real problems, it means that you will "meet", which means that your subconscious mind has this tendency.
The ex-girlfriend has the intention to marry you, and in her dream, she should be "together". Contrary to the real question, the root dream is interpreted as your "affair" just gathering, which is unsuccessful.
So the overall explanation is that your love life will have some twists and turns, but it won't hurt in the end.
