So just to summarize this
You have unprotected sex with a married father of 3 who continually lies to his wife and has not left his family as of some years later to be with you.
That means you could already be pregnant with a child of a father who will never care for it.

I don’t judge you for having sex with him
Im not judging for being with him although he is married.
Im not judging for you being delusional by believing him to change and to leave hi family

But I’m judging you for getting a kid wich will Most likely not have a real social father. Im judging you for using a unborn child as a blackmailing Potential.
And I’m judging you for not thinking ahead and being selfish.
