There have been studies that show that going on or getting off birth control has destroyed marriages. In some cases if you met her while she was on, and gets off it may cause issues, if she wasn't on and gets on after she meets you that may cause issues too. That and birth control affects levels of hormones which regulate our general moods.
In my case my W switched methods, and things have dramatically changed for us. Of course I've also been DBing my butt off for the last year so that has helped too. As for her saying she misses you and such it's a good sign. Keep at it. Remember to return roughly 85 to 95 percent of the affection she gives to you.
It sounds childish but she needs to feel that you will be there for her if she changes her mind, but that last 5 to 15 percent you withold is so that she is reminded that she needs to commit to get 100% and that you won't wait forever.
