You say she 'initiated recovery' but it sounds to me like there is still a lot of typically alcoholic behaviours running riot there. Is she in any kind of program or receiving support? If not, then it may be wise for her to seek some and get properly comfortable with herself and explore ideas about how to treat others in a loving way.
Are you in recovery as well?
If you do ask her to marry you now, it will be like you are giving her current behaviour the green light. Under those circumstanced I suspect that she will be very unlikely to change how she treats you.
