<human>: Can you give me a shortened version of the text?

We met in college.  She was a virgin, I wasn't.  

At the beginning of our relationship she asked me: if we didn't have sex till marriage if that would be a big thing?  I said no.  A week later we had sex.

We've been having sex since then, and now she lives with me.  

However, she's been having a lot of anxiety about us and we've been attending church more frequently now that I graduated.  This has somehow led her to tell me that she doesn't want to "live in sin" and that we shouldn't have sex till marriage.  

I agree with her from the christian point of view.  It's just extremely hard to cut out something that you are used to having.  It's just like any kind of diet, you are used to drinking coke and eating icecream but now you can't.  And you know it's for the better, but it f*cking sucks.
<bot>: My question is:  Has anyone else been through this, having-sex to not-having-sex situation?  What's the normal thing to do?  Can I survive?
