Well, If She loves you, She will forgive you, Tell her, but be sincere,
Don't act like her father, sometimes things happend so she has to undersatand,
I'm a girl and I don't like that my bf act like my father, maybe it works on some girls ,but it's not a fact , And if you choose her, don't treat her like I don't know how the society expects me to act, be you , It depends on your relationship, How it was, everybody is different, so I wish you luck with your gf.
