Man, have i been here before! Basically shes immature, I don't know how old she is but if a person plays games like that then it wouldn't matter the age. She wants attention, she wants a lot of it, from you but she doesnt want to be with you because she wants to explore and look for someone else that can give her attention.( dont know why yall broke up but...) Trust me Ive said I been here before because I did it to someone I was with.I wasnt really sure if I loved the person I was with or not but I told them I did...because...well... they were cute, bought me things, good sex, or some other reason. I told them that I loved them and I cant see myself with nobody but them, while talking to someone else. So by doing that I still held on to attention that I knew wasnt going anywhere. Show her that you bout to move on and see what she do! Tell her "look, lets not be immature about this, either you want to be with  me or you dont, dont waist my time or yours, if you say you love me then we should be together, if I did you that bad where theres no chance for us then stop with the mixed emotions"

Oh and mini chicken burgers are BOOOOOOOMB!!!!

I recomend being blunt with her! It might just work to see what her intentions are. 

I'm not good with all the stupid hints and games girls play, but if I were you, I'd just ask her straight out and if she still continues to mess around then just say 'fuck it' and drop it. Do you really wanna be with someone who tries to make you jealous and plays these silly mind games with you?
