I would be very tempted to start a R talk too. She appears to be wanting you do be the husband still even though she burned the bridge. she effectively fired you from the husband position but still wants the perks of having a husband.
Boundaries are needed, that's for sure. I think it is fair to ask her what her expectations are. I also think it fair to be gentle but form telling her what your boundaries are now that you are in separate homes. She no longer gets to have you as a partner, this is the consequence of a separation/divorce.
