Following a difficult separation, I'm having difficulty navigating co-parenting of my two young boys (under 10)
We have an informally agreed 50/50 arrangement which was working OK until recently when my ex has become more difficult and is attempting to alienate the kids from me.
He will often try to change arrangements at the last minute saying the kids don't want to come and are upset. He remains in the family home and it is difficult for them as that's the home they have always known. I have an excellent relationship with them and they are always happy once settled with me.
He has recently begun a romantic and sexual relationship with the children's live in au pair who is nearly 20 years his junior. While I'm far from pleased about this, I realise there is little I can do and just need to move on. I never talk negatively about their Dad and don't ask anything about his new partner etc. He has told them lots of lies about me which I just correct gently if the kids mention.
They went on a week's holiday recently and my youngest really struggled. He had an accident in a swimming pool which scared him and said that the new gf was mean and making fun of him.
I'm trying not to get into conflict and maintain the usual schedule with as little contact as possible. However the kids mentioned that their Dad is planning to take them to Thailand for 3 weeks in the summer which I'm just not comfortable with.
He is a heavy weed smoker and emotionally abusive (narcissistic personality). The advice I received is to stay out of court if possible and minimise contact. To hold firm on boundaries and provide a secure and steady environment for the kids.
I would appreciate advice from anyone who has experienced similar issues. Thank you in advance.
