Don't worry about any "mistakes". Avoid them but don't dwell on them when you make them (because you will make them).
The challenge is getting to the point where you can let her go to do whatever she feels she needs to do without shutting down completely, i.e. to lose love for her. Some people feel that is when you are over someone. I disagree. IMO, you can love someone and let them go, without losing your own self. You can have a life, focusing on other things. I believe this will enrich one's life tremendously.
I am still working on that.
