Teen pregnancy

Hi , I want others opinions

Me and baby daddy were newly engaged but less that 24 hour later I found out I was pregnant.

He was fine until 3 days before my 12 week Scan when he started to pull away

Before I got this far in my pregnancy we sat down and spoke about our options witch we decided to keep the baby

Now he doesn’t want the baby saying he’s to young and is demanding I get an abortion

This isn’t the first time he’s asked me to get one as we had a previous pregnancy as I was so early I did it he later promised he wouldn’t do it again

Now went back on his word

I have asked for us to try and work threw this I’m giving him time to think

He knows how much I would love to be a family

I don’t want to do it alone

What should I do ?
