Panicking. Is this normal?

I'm 4 months free of my narc sociopath. My story is on the tell your story page if anyone needs detail. But he moved from my home to another woman's home within 2 days of meeting her and is engaged to her. They have now been together almost 3 months. I sent her an email warning her and washed my hands. I'm trying very hard to move forward and I'm getting therapy.

My daughter out of the blue asked if I had heard from him. I told her not in 5 weeks and we don't have to worry about him anymore because he's getting married again. She oh good we are safe for a little bit then. I said no forever he doesn't want to be with mommy anymore it's gonna be ok. She responded 'mom ur crazy if you think it's gonna last with his new girl friend and the second he needs money he's coming back to try and get you because hes never gonna let you go because you make way too much money and I feel like its gonna be soon!'

I don't believe in premonition but I believe kids are very intuitive. So I broke the rules and looked at his new girlfriends fb page. I know I shouldn't have but I needed reassurance. Well first thing that hit me is she has 2 boys (9/10) and one is autistic. The second thing that I noticed is she changed her work status to stay at home mom today. She worked as a nutritionist at a school on a military base for the last 8 years.

I'm in a sheer panic. My best friends son is autistic and he requires a lot of special care. And her son appears to be not as functioning as my godson.

My ex hates children. He would tell me he wished my children would die because they take from him and he shouldn't have to share me or my income with my children. That I was his. He especially hates the boys. I have a 17 year old son and my ex would tell me he wished my son would get put in jail so he would get raped and he graphically described the rape until I ran screaming. I ended up sending my children to live with their dad so I could fight for my freedom without worrying about their safety. He has been with 7 women and all 7 of us have had to get our children to safety. He even has 3 children of his own he hasnt seen the 9 year old since she was 9 months. And the 17 and 18 year old since they were babies. He calls his 9 year olds mother and tells her he wishes her daughter was dead so he didn't have child support he hates her and she's nothing but a burden and wishes she was never born. He always says these kids take from ME!!!!

Anyways my panic started with my daughters comments. Then finding out she has 2 children and one is autistic I really started panicking. Both for the children's safety and because he will not be able to handle that. Then finding out she's not working I flew into full panic mode!! This man easily costs 8-10k a month. He has to have everything and the best of everything. And if you don't get it for him he will throw temper tantrums like nothing you have ever seen to the extent of selling my things if I wouldn't give in so he could get his fixes.

There is no way in the world this man is going to support a 40 year old unemployed woman with two children one of which is autistic.

I'm about to pack all my shit and move for the 6th time in 2 years! I'm about to throw up in fear he's coming after me!!! Is this panic normal??? Why am I soooo scared???? I'm a strong independent woman who shouldn't be afraid!!!
