Need support 😏

So my ex husband found out that I'm pregnant like the day after we found out when I asked him to keep his dog from jumping on me (he picked up immediately). All around the same time that me and my husband bought a brand new house. He has now gone around stating to people that I am pregnant and he not only supports my new child but bought my new house as well...

Just because he pays support for our son doesn't mean he dictates/pays for our life...

I am going to loose it soon with all these hormones, anyone have any advice for me.

We haven't even told extended family 😡 nor our son! He thinks babies come from writing a letter... he hasn't wrote the letter yet!

Help 🤔
