Nice job T. That's a big step. Well handled. While giving her money and shielding her from the consequences from her choices isn't good long term, this is a short term transitional spot, and I agree with the way you handled it.
One thing I'm big on is having a mission statement, and making sure all of your texts/emails/phone exchanges are consistent with your mission statement. Avoid interacting unless you've had a chance to find your inner balance, so you're not acting controlling, punishing (by being nasty or cold), needy, etc. It's fine to go dim, but when a response is appropriate do so from a place of inner content. Be cordial back up to 80% of her friendliness. Don't try to show her you're doing well, let that come through between the lines of being nonchalant and relaxed.
Oh- one caution- don't copy text exchanges word for word. Change a few. I doubt she'd google search your last text message, but if you ever sent a memorable text that she for some reason searched I'd hate for it to lead right to this thread.
Keep going!
