He lives in an apartment, but the thing is HES friends with this girl, in the same building as he lives. shes named Diane and a charge of 20 to 18 years. in 16 on the road. But he took me sooo many times: I said to him, he loves me with all your heart and HES HES always txtin me credit. and really believed. until I learned he had talked to my mother on MSN. I know I should not have done, but I have his recording of conversations with him, to see what he says. Coz hes cheated me before, so I still dontknow I can trust him. Also, my mother had told him 2 .. I know all about ur girl? and he said to his fighting weight? ND started to say shes named Diane, and she is 20 and lives with her!
