Purging again

I've binged and purged the last two nights in a row and to be honest, if I could get away with doing it at home too then I would do. But my husband would know right away. He's already suspicious and I'm doing it out of the house. So I have to decide, do I stop doing it or carry on and throw away all my recovery. If I carry on, I have the choice of being honest about it and feeling like a failure, or hiding it and being a liar as well as a failure
