my boyfriend and i are crazy over each other but we also drive the other insane. i love him so much like its crazy its like the notebook love and the titanic combine, like hes my best friend and we are crazy for the other. like we will talk on the phone all night long and he always brags about me and what not like i do with him. but sometimes we get into these stupid fights and hell say hes done .... and then i think hes done with us and then i feel like my entire world is broken and ending and im crying and i feel like im about to throw up. but then i find out he was done with the conversation. i dunno i dunno why im so deep in love with him but i cant take it anymore, how can i get myself to get out this deep into love?
