Only you know for sure, tank. Protect yourself and don't get sucked in, if that's what you think.
The only thing you can go by is what is "normal". Is this similar to what has happened in the past? Your W contacts as though to re-connect and then you get drawn in? If so, what would make this time any different?
If not, then be pleasant but distant. Respond if you feel safe to not get sucked in, by at least acknowledging but not necessarily to every one. If you feel at risk, then do what you can to not place yourself in a vulnerable position.
