Is my GF losing interest and will soon brake up because i like her & really she's da 1 dat waned us 2 work out?

me & my GF have been 2geter 4 about a month & a few, but lately i have dat gut felling wer something is rong. 4 example da fone calls/ text wer evenly split now mostly its me calling & wen i call or text she doesn't reply back & wen she does call back its da same excuse i was sleeping but wen we do talk its always gud we laugh & talk 4 hrs, i haven't seen her in 2 weeks & she makes no attempt in trying 2 see me even wen i say i want 2 see her
