Pregnant of nex-situationship, I feel so alone

I’m a little over four months pregnant from my narc situationship. We have known each other for about 1,5 years and were exclusive.

When I told him I was pregnant, it went from ‘I want you to get rid of it’ and ‘I’m going to move to a foreign country if you file for child support’ to ‘I want to be there for you and the baby’, ‘we need to make a little nest’ back to ‘I never wanted this, you put me up with this’ in a matter of days.

The cherry on top was that I had to go through a thorough research to see if the baby was healthy. This included a CVS and a blood sample of both mother and father to exclude any genetic disorders. He wasn’t there for any support or appointments. He told me he would go take a blood sample and made an appointment. Through the clinic I heard that he cancelled that appointment again. I was so angry and disappointed that I ended all contact. A few weeks later we ended up having a phone call and he promised me to get an appointment. Of course nothing happened..

At days I feel so sad and left alone. Doing everything alone in a country where my family isn’t at (I live abroad). I’m also very sad that my daughter is going to have an absent dad like this. I couldn’t have had a worse partner than him to have a baby with. I’m not sure what the future brings and it worries me sometimes. Then again I feel so much love for this little human inside me and I reckon I will make it all work.

How to navigate this situation? I definitely have to file for child support, since the country where I live doesn’t provide a lot of child support and I can’t make it on my own. There will always have to be some sort of connection to him and it’s stressing me out.
