How do you get over your ex-girlfriend who left you for another guy who is more her “type”?

When I asked her why she did it, she also said because I didn’t have enough time for her, (we were in a long distance relationship at the time, but not originally), and she sayed because I was too sensitive. She broke up with me about 6 months ago, and two months later I found out she broke up with me for another guy. I feel I am almost over here I just need to know how to get completely over her. (this was also my first real girlfriend) what should I?
