Welcome back to MB. Have you told your wife about this girl? You should. You should also quit that job and never see her again. You can see the affect working with her has on you and this is a dangerous and slippery slope. Acknowledging it here does not eradicate it, the only thing that does that is to never see or speak to her again. You have worked hard to recover your marriage, no part time job is worth jeapordizing that.
