Rant/Advice please

Hi there, I’m needing to vent and also gain advice. I’m split from the daughters father since she was 8 months old. (I have a son too who is not his, and both were long term/long friend relationships).

Since I split from my daughters father, I’ve had nothing but trouble. His family think he is a golden boy; and he managed to even convince my family this. He lit me and A+E, sexually and emotionally abused me, to levels I didn’t know existed - and I would have endured quite a lot -

Obviously now we are not together, and it’s legal abuse, along with whatever emotional abuse he can fit in, which he does. He cares very little for my daughter other than for how he appears, and ends though I despise his guts, and his enabling churchy preachy family, I have still been nice about and to them. I’ve been nothing but abused from them all for years, and yes I have spoken to professionals in those years about it, those who witnessed his behavior and alerted me.

We are still in and out of family court for tiny things. He refuses to let his girlfriend meet me; and she ignored my greeting whilst at my daughters birthday party, where I sat alone, and she was in the group: she is a mother herself! My daughter had a recent tiny hospital appointment and my ex didn’t inform me until it was over. So, the visitors where the tinder woman who cannot introduce herself to me, him, and his overbearing family.
It has caused so much division with my own family. He is unbearable to deal with unless it makes him look good. It is difficult to explain unless you understand the psyche of a narcissist.

I do not know what to do but there’s my vent; nothing milked down. I’m not far off printing names but I assume that’s not allowed. I plan to go back to woman’s aid, but emotional and lethal abuse is hard enough to prove , when I have hospital records with my head bleeding open that he got away with.
I feel like punching the life out of him myself for justice: Sorry to say. I’ve never hurt a fly.

End vent/ thoughts welcome!
