You'll hear from her again, I expect.
She's using and no doubt he is too, so things will spiral downwards at some point
and it is quite likely she'll look for a soft landing.
I'm so sorry this happened to you but frankly you dodged a bullet here.
It hurts, but best to stay strong and no contact.
Maybe even change your number so you aren't tempted.
You'll heal much quicker this way and won't have expectations or disappointments.
She isn't doing better with a "richer" guy.
She cheated with another addict and they are both using together.
You deserve more.
