OP, the Freedom Programme is an information course. The groups are free to attend, confidential, and often have crèche facilities. It's women only. It's a 12 week course (2hrs pw) and operates on a rolling basis so if you start partway through or miss sessions you just keep going until you've covered all 12 sessions (each one covers a different topic).
You don't have to stand up and share your history, you don't have to share anything if you don't want to - you can just listen. It's not counselling, although the groups are supportive.
They help you understand the dynamics behind abuse and what drives it, rather than just giving you a ticklist of specific abusive actions to spot they help you identify any abuse. As well as what's not abuse, but simply being an imperfect human.
They teach what healthy relationships looks like so you have a model of what a genuinely non-abusive relationship with somebody who loves and respects you is like. Rather than relying upon "this man doesn't do the specific abusive things my ex did and therefore can't be abusive" they show you how to identify different types of abuse - different abusers behave differently so comparing one to the other to decide if s new person is abusive is dangerous and unreliable.
It teaches early warning signs that somebody will become abusive or is preparing you for abuse. It teaches you how a healthy relationship begins and progresses. It gives you confidence in identifying the difference and in trusting your instincts again.
It helps you understand how being abused has affected you, how you can recover from it, and ways you've been affected that you may not yet have realised because the abuse was normalised.
It explains the impact on children, even if they weren't directly targeted, so that you can have the knowledge and tools to heal them and ensure they grow up understanding what a healthy relationship is like and how they deserve to be treated in relationships themselves.
Basically, it sets you up for the future, to be able to protect yourself and your children, to be able to trust your instincts and make decisions you can be confident in.
They won't tell you what to do or judge you.
I'm not involved with the charity, but I've attended FP myself. When it was first suggested to me I didn't understand why, and I attended the first week still thinking "I don't know why I'm here, this is for other people, not me". I thought I knew everything I needed to know about abuse and that there was nothing they could say that would be useful or relevant to me. Once it started I quickly realised why I was there, why it had been suggested to me, and why I needed to stick it out. It honestly transformed my life for the better.
I hope you will give it a go. Knowledge is power. Take as much as is useful to you and then make your own decisions.
