What office?!? :D.
I had a long term relationship that started with us doing mad amounts of dope, but eventually transitioned into both of us "recovering".
It was hard. Hard. She gave me a lot of shit for jumping to Suboxone, cause she made it through without an aid.
A few months later she was back strung out and got on methadone. I resented her because I could see that she got buzzed from her dose. I didn't feel she was truly clean and there was also a jealousy element to it.
Shit got straightened out, but it was like the past hung in the air. I don't know.
I'm not trying to be discouraging. I think I'm mostly saying to expect some substantial growing pains. It's almost like being with a different person.
If you guys were truly meant to be together, things will smooth out. If not, they won't. It's something you'll see over time.
Try not to get nostalgic for the old days. It's easy to do. To day dream about when you guys were drug buddies.
Also, if things are rough, don't start thinking a return to using will fix things. It might make shit feel better temporarily, but then you're right back to start.
