How should I proceed with this?

The woman I'm crushing on said a few things that make me think I have a chance. But she said she wants to try to repair her current relationship (although her boyfriend is the one to blame for their current situation). And he saw the texts in which I confessed my admiration for her but not the one where she kinda sorta hints at her liking me in that way.

Here's a few problems.
1. She switches jobs at the end of the month.
2. I have no idea how I'm supposed to win her over. I'm beyond incompetent when it comes to relationships.

Help please...
