Too late to worry about that. You sent it. You have a bigger problem than her connecting with this guy. What she's doing today is merely a symptom. The more fundamental problem is that she views you as weak and she is showing you her disdain for your weakness. She didn't have to even tell you she was spending so much of today with this guy. My guess is that she is looking to see just how much of a patsy you are.

Stop sending her any texts/messages whatsoever. That will put her in the position of wondering what's going on with you. If she telephones you to speak to you, barely talk to her and get off the phone as fast as you can. Project strength! (Regardless how you feel.)

Things haven't been as rosey as you thought. She is having a hard time feeling much respect for you. Notice what the ex did in the past: He didn't give in to her demands that he "travel and explore" with her. He said, "No." and let her walk away. You could learn something from this guy. She has more respect for him than she has for you . . . because he didn't give in. This is an ego thing with her now. She wants to see if he still wants her.

Put some lead in your pencil and firm up. You are being played.
