Asalam aliakum Sister,
As a convert too I feel the same in some ways. But inside I know who I am pleasing and who I want to do things for and it is Allah.
There are alot of reverts that I have met in the same situation and feel like under same scrutiny. And unfortunately I don't have answers since I am still on a learning path.
Just be true to your heart and do things for Allah, and I beleive things will become easier in time. Try to pray the Salat every day and pray that Allah will ease this situation for you and he will.
Take Care Sister and InshAllah things will get easier for you and your husband.
