My previous denied some Aḥādῑth on the basis that some are fabricated. What was the state of his Īmān?

I got married to a Muslim man who dId not pray salat at the time of our nikah. After our first night together I told him the importance of salat then next morning he washed him self and told me he prayed salat. Another thing is he told me he only believes in some hadeeths because he says some hadeeths are fabricated. But he believes the quran 100%. his a born muslim. Now we we are not together we got a divorce. But it still hunts my mind and i would like to know if my marriage was valid. Please tell me. I have panic attacks because of this issue sometimes.
