Does she know you've been sober 4 months? You've told her? I think it would be very hard for her to accept your word after hiding it from her for 10 yrs.
Maybe shes' just pushing back a little for what you've put her through. Stay sober, give her some time and space; it might not be the end yet.
Stay positive and keep letting her see that your changing for the better.
I hope everything works out for you.
