Most Helpful Girl
I know you love her, but it was very unacceptable of her (imo) to continue texting her ex when you asked her not to…especially knowing he was being inappropriate with her (a girl in a relationship). Very disrespectful, if you ask me.

Personally, man. I'd expect the worst.
I mean, there's a chance that she's come to her senses and realizes how much she loves having you in her life, but there's a better-than-not chance that she's decided to break up with you or that she and her ex-boyfriend are reconciling.
When someone needs "a week to figure things out" that usually does NOT mean "I'm going to sit here for a week in my free time and try to work this out in my head". It usually means "I need you out of the way for a week so that I can do X, but I don't want to completely get rid of you in case it doesn't work out" - X usually meaning something like "try getting back together with my ex" or "sleep with that person I met at work" - stuff like that.
So, I mean, it could be that she wanted to try getting back with her ex and wanted to be able to tell him that she broke things off with you, and it could be that as soon as she mentioned it he was like "Um, no, I'm done with you, and I've been telling you I miss you so that I don't sound like a complete asshole" and so she's been trying to get in touch with you to pull you back in, but that's not the scenario I'd expect.
If she does want you back, I'd try my best to find out what happened to make up her mind, and what she did with her time off.
