Girl problem, please help?

This girl and i have been dealing and we've been really good, we hang out, text eachother a lot. On new years eve, we had a really great night together, and she surprised me with a card and chocolates on my birthday. Today, she went to a volleyball game and texted her after the game and she told me how a lot of guyd commented her, i actually got bothered but i played it off like i didnt care saying haha really. She then replied " yes.. -.- the guys were like lets go number 10, stretch it out when i was bending over, it was gross. But obviously she said that to prove shes fit and boost her ego, it really bothered me but i played it off saying, hahah maybe those guys like it.. looks like you got a lot of attention, feeling nice lool? advice? :S
