Surviving the Narcissist

So I’m pregnant and my child’s father ultimately ended up deciding that I’m not what he wants and now I’m just overwhelmed with the thoughts of being alone. I’m not really close with my family and don’t have many friends. I expected to have him through this journey so since I don’t, I just feel kind of lonely and lacking connection.

How can I get rid of the narcissist? It’s mine and my kids home so leaving isn’t an option (but I wish it was)

Financially I pay all the bills , rent, travel, stuff for kids but how do I get him out

I’m in the uk 🇬🇧 if that helps

If you wouldnt mind also saying how long where you with them for in a relationship? This may give better context.

So I bought my own house, pay all my bills on my own, and have my children with me most of the time why do i feel like I wanna still be with the narcissist? Like I know the trauma bond is huge. Been together 20 years. But i literally have all my finances in order by myself. Also, we have not lived together for a year and half. He got kicked out then. Like a year ago a police report was made bc he broke into my other house. Due to this incident i decided to move us all away. Now i feel dumb because i accept to hang out with him as a "family" some weekends bc I wanna spend even more time with the kids. Please help. Words of wisdom, anyone relate?, how do I block these thoughts because it is haunting me. No custody case has been done. Oh and let me add the brain fog can get intense. And it scares me. My brain and body are on high alert and the brain fog kicks in hard. My memory feels destroyed

Ive left an abusive relationship and now he’s talking about his mental health and mentioned suicide but won’t answer his phone anymore. His parents are not interested in going to check on him so I’m racked with guilt in case he really is in crisis but I know he isn’t a safe person for me to visit. I can’t stay home and do nothing but without the support of his parents (who just replied to my calls with a txt saying I should stay home) I feel compelled to go and talk to him. Sending police for a welfare check doesn’t seem like the solution-i think he needs someone who can listen and advise him-he won’t respond to police.
