Giving Newbie the benefit of the doubt, it seems possible that (former) Secondary gave you an email address that Newbie doesn't actually use. Yes, I am suspicious that (former) Secondary is pulling the wool over both your eyes and Newbie's. This might be a time to strongly consider meeting with Newbie in the flesh, assuming you even want to bother with the relationship after witnessing (former) Secondary's trickery.
Sorry to hear you're getting treated like this.
I hope you'll be able to meet with a good counselor soon.
