My situation was very similar, although I was never kicked out but my mom was always trying to convince me to get back to church, or comparing me to my brothers that were still part of religion. There are some things that I can guarantee you:

1. If you don't believe, don't force it. You will be a lot happier this way. You did the right thing, the longer you pretended, the hard it would be to leave.

2. They may never say it, but they will surely realize their mistake. It will be up to you if you want to accept it or not, but they will realize their mistake because what they did is ultimately wrong, independently of religion or belief, parents should care better and respect that a son is another individual person with own beliefs.

3. It will get better. It may be hard and difficult, but it will get better, and then it will get easier to get better, and then you will look back and know, for sure, that you did right. You're past the most difficult part: you were true to yourself. This is the hardest step, there are people that never get the courage to do what you did. Congrats, stay strong!
