You can contact her but it isn’t going to go how to think it is going to go. Do you really think she is waiting around for you to contact her again and will drop everything if you call her? The life that you have imagined her living after the breakup is just that, your imagination. She has moved on and hasn’t given you a second thought. There is no amount of money, words, actions you can do to fix what you did and win back her trust and love. Take the lessons you have learned from that and work on yourself.
