I've just got your email, and you're worried about your love.
What you should do is to accept what has happened before, then you will find the cause of problems that can occur but if you think you don't know what to do, I recommend that you try to understand with your lover, then you take her to eat dinner and buy flowers and gifts that you think she likes and give to her.
I know it is hard at first, but if you do not dare to speak to her, you will not be able to pass the problem to realize exactly what I was, so I request to you, and if you have a problem with anything, you can consult me.
