Im going on holiday with my family but my girlfriend isn't happy about it and she has finished me over it?

My mum is turning 50 and as a birthday gift she wants to take us all away on holiday for a week skiing. The only problem is my girlfriend is furious about the situation and feels she has been left out and that my parents hate her. This is not the case and ive told her but she wants to finish it she says she has had enough of it and basically it is over, I dont want to lose her and love her to bits What do I doI ve talked to her and said I cant help this happening and she said you can just not go but I said I cant its all booked and it will break my heart and she says im always putting them first, which to be honest anyone would in this situation they are my family! She is adamant though that i can do something about this and that her parents would never treat her in this way she just says I ve made my choice so its over, its just hurtful and the fact she went away last year with her friends and i didnt say anything, my mum cant afford to take her aswell its just all getting to much for me as she just says all this is killing her, what do i do?

There must be no big deal with that. Its a family thing she must not be insecure to what your families decision. Unless she has that money or you have money to sustain her to be with you during your mom;s birthday. For now both of you needs space. Just let your heat calm down.
