What do I do about this?

my girlfriend (were gay) is literally so amazing that all of her ex's at one point or another have asked her back and some other chicks send her y txts and me and her have been together for almost 6 months and we love eachother but what do i do about all these people wanting my girl? it srsly makes me so pissed off and sad its like why cant they just leave us alone? my girl isnt even conventioanlly pretty persay. its all her personality. i dont know what to do though what do i do about all these girls wanting my girl? i just wnat to beat them all in the face but i know thats wrong and wouldnt do that but it just pisses me off. what would you do if an ex of your girls was txting her telling her she loved her and stuff and y txts? youd be pissed off too. what do i do? thanks
