You’d love to help a loved one to help himself but it looks like he already has and now he has to deal with the consequences.
Information divulged at a late date looks like it will alter much of what you believed to be true. Call time out so you can process it all.
It’s hard to tell if someone’s clueless or just being misleading. In any case, wait for events to unfold.
You’re dreading a confrontation but see it through. Resentments have been building and you need to clear the air.
That office infatuation of yours is interested, but not currently available. Bide your time. He’ll need someone to turn to soon enough.
Don’t try to lighten a loved one’s dark mood. Sometimes people just need to be by themselves for a while. S/he will resurface when the gloom has passed.
