should I stay or should I go??

Thinking if I should break-up with my boyfriend or not....I love him so much...but I can't keep taking all of this disrespect. He's made me feel so low at times...and yet so high at others....he always tells me he loves me and that he never wants me to leave...but his actions say something completely different from his words...everyday its promises after promise which turns into lie after lie and apology after apology...I wonder does he even mean the things he says now...am I a game to him? Does he just want me around so that no one else can have me? I thought when you were in love it was supposed to make you happy and set you free...it feels like I'm a prisoner to my love for him...I wish I knew what to do. I wanna leave....but everytime I start to he switches up and makes me feel like he loves me again...he butters me up so good and becomes so kind like he was before..then as soon as he has me smiling we're back at square one. Him gone in the streets and me here alone trying to figure out were we went so wrong..
