Sometimes you can parallel parent, hold your head high, hand over your children, ignore the bullshit and counteract it with your children.
Sometimes other safeguarding issues are in place, so you have to drop off and collect children in a busy place.
Sometimes, bigger safeguarding issue arise, where the children have to visit the other parent with a safe person always around.
Sometimes, safeguarding issues are that big they can only see the other parent in a contact centre.
Sometimes the safeguarding issues are that big, the children simply can not see the other parent as it’s too dangerous.
Then the extreme cases where you have to move miles away.
Which ever contact or no contact you and the children have with the other parent, is fine as although all narcissist have the similar traits, they all have different levels of manipulation and violence.
Whatever your personal situation, keep as much as possible in writing from the start, In case they children need to see this when they are older, be prepared for an upsetting deep heart to heart with the children when they ask, just give age appropriate answers.
One thing that is the same in all of these situations, is the narcissist will never see it as been a problem caused by them, they will lay all the blame on you. They will twist it all around on you, to your face and behind your back.
So stay strong, trust yourself, know you are doing the best by your children, get extra help for yourself and your children if needed. Keep going. It will be ok. A child can grow and will thrive with one stable happy parent, even if they see the other parent once a year, once a month, once a week, or never. You have got this, now is the time to believe in yourself.
