I agree with the fixation on Limerence. It's best to leave that alone. Not a lot of encouraging information out there on that topic and will drive you to thinking about the end results which you have no control over. Focusing on her feelings toward the OM is also out of your control and doesn't help with moving forward.
Glad you posted about obsessing over it because I started thinking about it this morning and couldn't get it out of my head. I'll let it go now and not think about it anymore.
