I'm always available for call whenever physically possible, mind you I work in finance. Depends what kind of ownership of the project you take, but you should NOT be forced into it; That should have been discussed when you took on the managerial role, as obviously you didn't have full understanding of responsibilities. Personally I don't think there's anything wrong with that request (again it should be request not forced), but bigger problem is that you might have other hidden responsibilities and that is a bit of a red flag.

When someone with power over you makes a request, you can never be sure it's not forced, regardless of how they word it.

This is one reason that most organizations disallow romantic relationships between a superior and a subordinate.
