Hi @Sonniekia
The rollercoaster of abuse destroys your confidence and self-trust. Living with the constant stress is an insane amount of pressure to live with. So give yourself some credit for surviving each day, and being a mum in the most difficult circumstances. People who've not been through it can be quick to wonder and blame a woman with - 'why doesn't she just leave' without realizing that emotional abuse is essentially a process of entrapment that plays out over time.
Leaving an abusive relationship is not an overnight thing - it is a long series of very small steps. And yeah, lots of women have done this, and you can too.
You've taken the step to post here and be honest about how you feel and how it is impacting you. That is a big step.
Your next step could checking out the Women's Aid forum, setting up a personal bank account, researching counseling for yourself, signing up for a class/ hobby/study that will help you build your confidence. Try reaching out to family or friends to let them know what is going on - getting support is a really important step in the process of leaving, you'll need encouragement and cheering-on. Mumsnet has helped people leave abusive dynamics, so you can keep posting here.
There are also online groups you can join that are dedicated to helping women navigate and leave emotionally abusive relationships.
No matter how devastated and beaten down you feel right now, you do have a better future ahead without this man in it. It might take time to get there - but you can do it, and you absolutely deserve it.
