Girlfriend of 8 months has slept with 30 guys (20 years old)?

Anonymous
As i said my girlfriend of 8 months has slept with 30 guys. She's only 20 and most of them were whilst she went travelling the previous two summers. A few were my friends at uni before we got together. She also walked all over her ex, she cheated on him multiple times when she first went travelling. We briefly saw eachother for a while last year but she tried to let me down by ignoring me for a few weeks then slept with my mate. Basically we're going travelling together for two months but she's gone a month ahead of me and I'm not sure if she'll cope without being able to fuck the guys she meets travelling. my reason for suspicion is because when i asked about the amount of people she'd slept with she told me i simply don't understand what it's like travelling and how quickly you for strong relationships. I myself have slept with only one other person but she says everyone she slept with minus on 36 yr old guy were like mini relationships that only came to an end because of travelling. When i told her i was worried she told me she can't promise anything. Any thoughts? Thanks for any replies.
