<human>: Can you succinctly summarize the text in 1-3 sentences?

I'm an atheist. I've never grown up in a religious family, and when we did attend to church it was to be social. I don't have resentment towards religious folks, it's just never been a big part of my life.

Then I started dating Liz (we'll call her that), around a year ago. She is a very devoted Catholic, mostly because of her (half) Hispanic heritage. She attends a private Catholic college, is involved in the faith based organizations, and goes to church every Sunday.

It's strange that we are so connected to each other, but we are. Same humor. Same sexual energy. Same relatablilty. 

Her devotion to her faith set me aback at first, but we rarely mentioned it. At first, she wanted me to attend services, but I didn't feel comfortable and said no. Eventually, I felt guilty, and decided to attend for her sake. (go to mass sometimes, church-based events when I'm off work) I'm even attending Easter with her family at church.

This absolutely thrilled her. I never saw her so happy, and our relationship became stronger than ever. (sex life too ironically, church is a turn on yo)

However now I'm left in a strange predicament. I am becoming worried any mention of my atheism will harm our relationship. I'm still non-religious, and hold the beliefs I do. I'm not ashamed of it, and never will be. 

But I can't help but feel my dis-belief is a definite negative to us. Just a sinking feeling eating at me. 

Can anyone provide insight and help?
<bot>: Worried my atheist beliefs are a negative to my relationship with devoted Catholic gf. Don't know if there is a solution. But just left empty inside.
