So idk he probally lied then he says he cant call bcuz the housephone is broken...now I havent heard from him today atall n ive been calling..but last night he hit me on my yahoo again sayin im worrying n everythings ok he has no reason to lie to me but I feel takin for granted I texed his mom no tex back..i dont believe the phones broke...we been together for 3 years any help??? O yea im the one in the relationship who has the job pay all the bills give him anything he needs...i feel used...i love him idk what to do???
