17 and still a Virgin... Am i a bad girlfriend? What am i doing wrong? ?

Your not a rubbish girlfriend. My first girlfriend was a virgin, and I thought she was perfect, we went out two years (she wanted to have after 3 months and I told her to wait atleast another 2 months to be sure if she wanted to) 2 years into the relationship she dumps me after I bought her a car, and took her to south carolina (total of like $15,000) and tells me that since she lived a hour away and we only saw eachother on the weekends to afford the gas she had been doing stuff with other guys a year into the relationship during the week days. I cant stand the idea that I would have to be with a girl who is not a virgin, I wanted something special and just wish there was a girl out there who was right for me and is saving herself but I not longer feel like I deserve it because of that relationship and losing my virginity to her. It's a crappy situation to be in.
