You'll be fine! My fiance started vaping about a month before I did. The transition for her was a challenge to say the least. Especially before I quit! A lot of her girlfriend's smoke, so temptation to smoke proved a daunting task! When I started vaping it was a painless transition for me. Though she was happy for me, there was a little resentment as well. She's been vaping for about six months, and occasionally smokes a cig or two, but that's it!
Though I wish she didn't smoke at all, I take solice knowing it's no longer two packs a day! Probably six cigs a month. If you cut a few out a day, the day will come you don't have to cut out any! Good luck, quitting is difficult. Don't be ashamed to do it at your pace. Just the fact your doing it is a huge success!
