Need friend help very very bad?

me and my friend best buds for more then 2 years talked every night texted, talked on xbox hung out once a week inless each other were busy. We are both 17 now and he got a girlfriend. That girlfriend dont like me so therefor she doesnt want him being my friend. I havnt hung out with him in 2 months havnt had a conversation with him in 2 weeks since its summer i dont see him in person and he refuses to answer my texts anymore and refuses to even talk to me. Are parents started to get involved and when my friend was asked why hes ignoring me for the past month his answer was im annoying him i text him to much we texted every single night talked on xbox every night before he dated he what do i do we havnt talked for 2 weeks its driving me insane he posts on facebeook when hes with friends he knows that would tick me off to see hes with them and completely ignoring me. I dont know what to do i feel betrayed but would never wanna lose him as a friend so is there anyway i can talk to him rember he wont answer my texts or anything.
