well , me and my girlfriend have been going out for 2 years and its been on and off , but we love eachother and everytime were together like at school or something and some other girl looks at me and says hi and smiles then i just say hi back but i dont look at them with a flirty face just like a hello there kinda hi . automatically she thinks i like them ! when i dont ! and i tell her i only love and like her thats it . and she gets mad at me but when she sees other people she actually runs up to them and gives them a big hug and a huge smile . like i dont understand why she does that all the time . shes been breaking up with me for saying hi ' or talking to my own family on facebook like my sister or cousin . while she flirts and talks to alot of people and i tell her how i feel but that just makes her mad at me even more . like what am i suppose to do? why does she act like that i cant do anything . i dont try to do anything hurtful thats why i dont talk to anyone but her and my family . i need help what can i do ?
sorry for it beeing longg .
