Im boring to him

My “boyfriend” is always on his phone and when i come next to him he locks his phone hugs me and pretends hes sleepy and closes his eyes. Once a notification goes off he opens his eyes goes on his phone and doesn’t say one word to me until he is really about to fall asleep and hugs me and starts snoring.. and i have found him flirting a couple of times and hve forgave him.. we barely kiss and we have sex like every 2 days... i feel like we are a 25 yr old married couple and we are just 2 years into the relationship.. i feel unwanted and like i am already boring to him.. im a very pretty girl i get alot of attention from men and he has made my security level go down hill... i want to leave him but emotionally its hard for me.. help anyone ??
