NGL, that sounds like a delusional 21 year old move to make.

>Still dealing with baby daddy drama from past relationship. And our entire relationship you had another girlfriend.

>Sign me up!

Sounds unreally desperate.

And we're sure the baby is not his, right?

I am sorry that you had to find out this way and go through this. But you dodged a massive long term bullet.

The fact your ex is so keen on keeping their relationship going, shows how low of a person he is. I bet he loves the fact that he's got a 21 year old wrapped around his finger. He manipulated you the entire time, and is doing the same to her now. He is not a good person.

That's their problem, and no longer yours.
