To answer your question, a resounding yes. I have 3 children, at the time of the divorce they were 12, 14, and almost 2. Midlifers think like children, so they put themselves before anyone, including their children. They also try to exploit your weaknesses, concerns, anxieties. My ex knew my children were the most important thing in my life. I had to make sure I kept my emotions in control and calmly set boundaries with him with the children. Often, the boundaries had to be repeated. On occassion, I had to invite my lawyer in on the boundary setting. It was a battle at first, but has improved considerably. True Ml'ers try to push your buttons and try to get you upset. They feed off of this energy and power. The more control you have over your emotions, boundary setting (often in writing) the smoother things will be. They will fight the boundaries but you have to maintain consistentsy and not waiver in any way. I hope this helps.
