Step Families Support Group
Traditionally, a stepfamily is the family one acquires when a parent enters a new marriage, whether the parent was widowed or divorced. This community is focused on many of the relationships and issues that may arise within stepfamilies where you may find answers from some members and you may help other members with their questions.
A good counselor will let everyone speak, will not let it turn into a "beat up session", and will step in when necessary. So far I have been most impressed with the co parent counselor. He stayed very neutral and tried to point out positives on both sides. It helped my ex and I work out some issues w/ out getting into attacking.
That said - not all counselors are created equal! We went to one before our divorce and she made me feel horrible every time I went there, obviously taking my ex's side.
So be sure you find a good one, that listens and steps in to help facilitate the conversation. I really think it makes all the difference. Its good to walk out of there feeling better then when you went in, not worse!
