180 Counterproductive?

[oops13]

I'm having trouble navigating one thing, and that's the fact that I haven't set any boundaries with the OM or blown all of this open. I think she doesn't know that I know, and I'm almost okay with that from the perspective of not wanting to force them underground more.

But also, early on, when she told me he wasn't anything, I said "oh okay" because I didn't want to display any jealousy or insecurity. This makes the whole vacation thing awkward. I may need to assert more that I do not want to go as just friends next time it comes up, but I cant decide if I want to confront about the OM. I'm not even sure she knows what she is even doing is wrong, but the grass is definitely being watered over there more than my grass. Im temped to tell her that if she "wants to work on us" as she says, that she needs to back it up by ending her inappropriate conduct, but doing so reveals that I know, and I'm sick of talking about the relationship any more than I have to. But, in being cool about it, I'm also leaving myself open to being weak perhaps.

Also this morning she said ILY and gave me a hug when I left. We made eye contact and did the peck while going out the door kiss. It didn't feel like pursuit, but I'm being wary.
