Of course they don't want you to leave, it inconveniences them.
If they're not even bothering to offer a raise or perks such as "work whatever hours you want as long as the work gets done", they're just trying to keep you around until they're done with you.
Did anyone say anything to address your fear that you were on the chopping block? If not, run, don't walk, as your bosses just want you around until they can get rid of you on their terms/timetable.
