Those are the only two things I've seen work. If #1 turns up nothing, then proceed to #2b. And in the meantime, GAL your ass off, and become the better option. Best case, you'll attract them back, and at a minimum you'll become a better person that will be more attractive to SOMEBODY in your next relationship.

I may need to review all the acronyms here, but does somebody only count as an OM/OW if the relationship is sexual? There is definitely an OM on an emotional level, and to be honest, she had another man (married) back at our previous station who she also became very close to emotionally. In this case I found that she had sent nude pictures to the OM here. She claims that there is nothing else going on, and that nothing else happened, and I haven't dug any deeper in her texts/messages to see if that's true.
The GAL-ing began a few days ago, and in fact our most recent conversation about our relationship (she initiated) had me letting her know that that's what I was doing. But at the same time, or as a result of trying to be more independent, she's becoming more affectionate, taking me out on day, "dates," (when I'm available), and things around here have just been more pleasant. I'd hate to get false hopes that things will work out, but it's nice to be noticed by her again.
